I agree. Unfortunately with our warped justice system if any vigilante bikers get lifted, they'll be locked up and the thieves will walk away with compensation. Planting a bait bike also won't result in conviction as it's entrapment.
I welcome any kind of action against bike theft, but whatever happens I still don't believe it'll be enough to put off the organised criminals. It may scare off the petty thieves and joyriders, but not a lot gets in the way of the gangs that are involved. We'd need an all out war for any REAL result.
Something needs to be done, there just isn't an easy win.
