Agreed, its kind of funny that this is the same forum where not so many months ago people were praising that Gurkha who fought off a gang of armed train robbers and killed a couple and now some people are saying this guy was wrong :S
The Gurkha killing the train robbers was not even remotely the same as what has occured here as the facts speak for themselves. A group of bandits armed with various weapons invades a train and starts robbing people. To make matters worse they decide to try and rape a girl. There is no mistaking the intent here when people are having their goods forcibly taken from them and they are ripping the girl's clothes off.
In this current case it as not at all clear what was going on. It
appears to be a botched robbery. But by the same token it could be something very different. I gave an example yesterday, so perhaps a few others are in order:
The "homeowner" as in fact a nasty drunk that smacks around his wife. He finally smacked her so hard one day that she couldn't hide the bruise anymore. Her brother found out about it and gathered up a few mates to head over and give him a beatdown. Things didn't go they way they planned. Who is the bad guy here?
Try this on for size, as it might hit a little closer to home to the seasoned internetter. The "homeowner" was in fact a internet scammer. He conned a bunch of people out of their money via various internet aliases over the years and the police just didn't find it important enough to do anything about. A few of the people who got scammed got together, figured out where he lived, and went over to get what they could out of him. Being a con artist he kept a weapon handy in case anyone ever confronted him. Bad guys not seeming so bad anymore? Could they perhaps be victims?
Lets go back to something a little more mundane. We are seeing the tail end of a long family feud. People from both sides have been fighting back and forth over the years, breaking into the others property, slashing car tires, and generally making each others lives miserable. None of this ever makes the media is it is just too commonplace. The stabbing was just a result of one of the incidents getting way out of hand. Now we have some prior motive, and that mucks up the heroics of it all doesn't it?
Again the point is that until the facts are sorted out the police are 100% in the right to detain him. To do otherwise would be negligent.
