Sometimes a person has to break the law to make sure justice is served.

One person comes to mind when I read this.

Bat freakin' Man

Ah, the vigilante.  What to do, what to do.  Really the only reason why he's here is because the police can't do their job properly.  In today's society (or at least here in BC), we have one of the top notch police forces in the world.  We don't need "heroes" like Batman to come save the day.  There is no need for anyone to infract any of the rules to make sure justice is served.  That's what the police are there for.  If you sense trouble, call the police.  If you are in trouble, call the police.  Even if there's no trouble, call the police, because you never know when a sniper is pointing his scope at you.

He sees you when you're sleeping...

I'm just kidding about that last one, but seriously, never try to be a sacrificial hero.  We have specially trained people who can do their job well and effectively.  Maybe it's time we start putting a little more trust in the authorities.
