If you’re paranoid about prying hands, then consider the No-contact. The jacket utilizes a 9-volt battery to deliver 80,000 volts to anyone who touches you while the jacket is armed.
There is a key mechanism that engages the system. A rubberized layer prevents it from shocking the piss out of the wearer, but I suspect it’d be relatively easy to accidentally shock yourself.
Equally shocking is the $900 the jacket will set you back.
