Welcome to Mississippi

ok then

How do the workers get in on Monday?

Break a window or pick the lock on the back entrance.

That's to keep you yanks from takin' without askin'!

nice, however they leave themselves open to prosecution as it's illegal to booby trap with the intent to maim or kill

Yep, illegal.

I an envious of this theft protection. This kind of thing should be legal. The gun is clearly visible. If anyone attempts to break into this store, then as far as I am concerned, they are taking their life into their own hands.
