My advice is don't bother with the cops. They almost always don't give a crap about the right and wrong. In the cases where both parties did something they may have to defend themselves from from the pigs, they will often go full force towards screwing over both parties, or doing so to the easier party to prosecute and fill their bust figure quotas with, I.E not the one who is a vicious thug that will be experienced as to how to lawyer up and manipulate the system to walk out laughing, and instead bust the guy who just got assaulted and instead of getting beaten half dead, left the thug in question in a whimpering, bloodied heap on the floor.
If you just had gotten stabbed, and never even seen it coming, or some such incident, or got robbed without raising a hand to defend yourself, or maybe dropped a guy out cold when you just had to escape from a huge pack of vermin out to beat you to a pulp, then perhaps, from the point of view of not getting questioned or attempted prosecution (while you may well have been in a case where there is no damn WAY you would be convicted in front of a court, doesn't stop the filth from trying) but has no bearing on weather you would set off a war with the scum responsible who you got nicked.
Save the cops for extreme circumstances, if you ask me, they are as dangerous to get involved with as the scum themselves, often as not.
It adds the danger of being marked as a snitch also. Which would truly enrage the guy, and most likely get him to get his boys after you.
Most thugs of that nature are real brain donors, complete stupid fuckwits, that will invent a 'cause' just to get in a fight, it doesn't matter what it is, that kind of scum, if you were turned the other way round, walking the opposite way, get your attention, then say something to the effect of 'what the f**k are you looking at, dick, time to get smashed in', just for a putative cause to start a fight. They go out looking for it.
Stupid as that is, and as big a pack of cretinous thugs as their chavscum ilk are, they can usually mentally process, just about 'I tried battering XYZ person, and found he was a whole lot harder, lets not do it again or next time he might actually beat me to death, or pull a knife'
I.e something along the lines of 'me nasty mean thug...but me leavie other guy around, he gorilla, he make bad nasty scumbag hurt lot me not like hurt, hurt painful and painful bad'
Not always the case, some will get vengeful and come looking, but when you get attacked by mindless trash like that, there is sometimes no other choice than to beat the devil from the tosser or tossers trying it on, unless you want that happening to you instead.
Kevout-careful what you advise, very careful. Some cases it might be the right thing to do, but it is also very dangerous to get involved in the legal side of things-if the case fails, or succeeds without the trash facing a jail term and being removed from the ability to strike back, it can leave you having to deal with an army of his friends, with him leading it, baying for your blood, after getting merely fined, put on community service, or wrongly getting away with it entirely.
Better to flatten the ***, or just leg it...depends entirely on the situation which is the better idea, and its often impossible to tell, before you do either, sometimes getting away, from somebody who doesn't know who you are, and just jumps a random person, just running for it, is the best thing, when the thug knows who you are or where you might be in future, or is someone in a position somewhere, such as college, etc where you would have to see them on a regular basis, sometimes the only way to stop a future load of aggro, is to put the fear of god into him, by leaving him a battered, torn up mess, and running may mark you as a coward/easy soft target, but other times, beating the scum responsible senseless will just set them off and start them coming after you longterm.
Always a bad situation, and very likely, impossible to know which of those courses of action is the correct one, that will bring less or no trouble, if possible, in the long term.
But if you have to, don't hesitate to act, and don't try to fight 'honorably', thugs don't play be the rules, and neither should you. Those who hesitate, and try to not use 'dirty' tactics, are the ones who thus find themselves lacking the capacity to strike a crippling blow that will incapacitate instantaneously, and not just make the aggressor more angry and determined.
If you have to fight, make it quick, make it brutal, and make it effective, go for a pressure point, strike hard to the family jewels, kick a knee joint and snap it, followed by a headbutt to the nose, punch in the throat, etc, if you leave the aggressor up and standing, it just gets them angry. Losing that sudden element of surprise, and an instantly incapacitating reprise blow, then you are at a major disadvantage in that sort of situation.
Hit hard, injure/incapacitate, make it count, make it something that will, no matter how hard the attacker is, remove their ability to act further, follow it up while they are down, with something equally effective then run. Don't hang around, just get away, and be glad the other bugger got hurt and not you. There is no guilt attatched to defending yourself, or another from being brutalised, it is simply survival, or defending somebody who would otherwise be the one to end up hurt or killed.
I've been in more than one such situation, and I have been on both resulting ends, I've got knocked senseless, and the pigs did nothing, just refused to act, even after the same scum came after me repeatedly.
On the other end of the scale, I once had two thugs try jumping me, no reason, I was walking to buy some snacks, tobacco, general purpose commodities from a shop, and was attacked by two of them. On immediately found themselves on the end of a flying kick hitting them right in the face, completely flattened the guy, the other thought better of trying it on and left, the other got up after some time and ran, I myself immediately left the area, after getting my stuff (I wouldn't have bothered, and would have gone somewhere else, if not for the fact that I was yards away from the shop, to avoid the possibility of the guy who ran for it first, coming back with a horde of angry chavscum friends)
And again, I've stabbed a guy with a metal bar before, after a first encounter where he just came up and smashed my face in, twice, minutes after the other, then seen him again, got knocked the f uck out, got the bacon to try and deal with it, both times not managed to do a thing about it, the guy in question is a serious, dangerous hard case, pretty sure he has been locked up now, don't know if he is out, and still had to fight the guy again, the next time I bumped into him.
I'm hoping I don't see the nasty little creature again, or that he either has been, or gets locked up for a long time, he is a dangerous guy, very much so, and if I do run into him...chances are, my choices will be either be beaten the shite out of, or maybe stabbed-or get in there, if I can manage it, so fast and hard that I can manage to cripple him permanently.
