Matt asked; "Now how many people do you know have a bump key?"

Probably a lot of crooks and burglars have them among their tools of the trade. If you click on one of the several links provided with the video ... it shows how 'easy' it is to make one (takes about a half hour).

These 'skills' are well-known among the prison population where many criminals are schooled in advance of their release back into society where some of us (unfortunately) become victims.
