Just duck tape the torn part, when people see that you can't even replace the torn part they would assume that there is nothing of value in your jeep
Whoey can tell you a horror story about an old buddy of his that mounted a bunch of razor blades behind the dash panel so when someone would reach behind the panel to unhook the stereo they'd get ripped up. The guy who eventually did it was so upset about having his fingers chewed up that he carved up the dash pretty good with a crow bar.Def
I believe that's pretty much what happened... the attempted thief got caught at the hospital with hamburger for fingers... and the owner had a destroyed dash covered in blood... not exactly a great theft deterrent...
