Brilliant idea!!!! Anti-theft

I just thought of a brilliant idea and had to share! I have been reading lots of posts on social media surrounding vehicle theft. Around my neighborhood and many other places there have been a huge amount of thefts of vehicles. I've come up with a brilliant idea however I'm not sure it is humane. What if you could stick a nice 10.00 bill on your dashboard to attract a thief then when they go to open your car door without the key or key fob it springs open like a mouse trap and snaps them in half!!! Some could argue live traps may be better but I'm thinking it's just not as effective. I think the risk alone would make a thief think twice. Heck why stop at vehicles have them installed on your house doors and windows as well. For all you anti gun people this should keep you protected as well! Win! Win! We would have to fully brief rogue teenagers because sneaking out wouldn't be an option!
