Out of Context
Not just bike thieves, but all thieves should be shot, Texas has it right, a trespasser steps on your property, you have the legal right to shoot them dead, and it works, nobody in their right mind commits crime there unless they're out-of-staters who didn't know such a law exists, which they find out about just before the hollowpoints make impact on their bodies... 
Over here, the innocent get blamed, "Well, you shouldn't have left it so unsecure", as if it's somehow our fault, and when they do get caught, it's slap-on-the-wrist and "Now don't do it again, here's a lollipop, now go home!", not tough enough and more of a reward than a punishment, just look at the mockery made about ASBOs, they were used like some trophy thing that had to be acquired to gain some sort of status, so they worked about as effectively as putting out a fire with petrol... 
Have you got that right?
As I understood it you can only use lethal force if you are defending yourself not your property and not far removed from the UK I suspect in that technically trespass in itself in not illegal.
Here in Wales you can only shoot somebody dead if they are English but you must use a longbow.... so it's probably quite an old law. Other than that you can recite 'The Four Branches of the Mabiniog' to them in Welsh until they die of boredom or beg for mercy and promise never ever to come back.
Bring back the stocks I say and make them watch Jeremy Kyle 24/7 for a week. 
Well, the thing my Texan friend always states is you have to make sure they're dead, then that way they, the recipient of lead poisoning, can't argue that they were there for some other reason and land you in trouble for shooting them, but, if they have no business being there, then they shouldn't have been there in the first place...
