Fluck em. You come into my house, illegally trespassing to injure me or mine, and I'll use you for compost.
In my youth, I lived in Jo'burg (an affluent region in South Africa); murder rates were high even for the times due to hijackings, robberies carried out in the day, etc. It's worse now.
Anyway, I recall the entire block around my neighbor was the only area in the entire city that had never in the years before and while I lived there been burglarized, attacked, stoned or any other form of crime visited on it. Criminals were too sh*t scared. See, my neighbor owned a variety of shotguns. And he didn't shoot to wound, he shot to maim. Never to kill, though I'm surprised given that the reason he had that attitude was due to his daughter being assaulted in his own home. He's since long ago moved away, but according to my parents the local riff-raff still cower and cover their "members" when you mention his name.
The situation there is pretty grim, but crime is going UP, not down in the UK. Rape, burglary, assault, vandalism is rife now in the smaller towns, and worse in the bigger towns.
And what do plods do? Break speed limits gleefully without their lights on, in personal cars (while ambulances get dragged to court for rushing to the scene). Assault people in the streets holding camera's without any reason whatsoever. Shoot (and kill) innocent travelers in the train station. Jeez, I wouldn't be surprised if they're only p*ssed because they and their buddies are the burglars themselves...
Criminals give up their rights the moment they break into your home with either dishonorable or illegal intentions. It's up to us to tell them it's unacceptable behavior; since the plods couldn't be bothered to even try - or might even join in if given half the chance.
