Upon that realization, they usually move on to the next victim, unless
your car is that rare one they want, then they may return with proper
tools.



I have a set of bits and a handle for these types. So far I've only seen
them in telephone company connections.

I wonder where you can get these screws? I can't recall seeing them in
Lowes, Home Depot, Tru-Value, etc. though I've never specifically looked
for them there.

See tamper proof fasteners: Also has "UN-DO-IT" REMOVAL TOOLS", page

Helped the neighbor install a metal security door the other day. ~ 4"
one way screws to fasten the frame to the brick molding. A special
bit came with the door to drive them in.
