That sounds like a good idea on the surface, but there is no way any criminal would be ok with being constantly checked for wires by their peers. You'd basically be showing disrespect every time you do it. Remember, criminal organizations are run as a brotherhood. You undermine that cohesion/unity when you are constantly checking each other for wires.
"Disrespect"....If that's the main reason they don't check for bugs and wires, then the Mafia has really become like Bloods and Crips etc by mentality (apart from the violence / "easy trigger" aspect). In that documentary series called Gangland, during interviews and interrogations, the word "disrespect" seemed to be in the center of their whole universe, I have lost count of times when their actions were motivated by "disrespect", not even power or money....
-Why did you kill him?
-He disrespected me!
And everything can be included in the concept of "disrespect", ranging from a "wrong glance" towards a member of another gang when you are crossing the "wrong" street, to serious things, like being cheated on millions of drug money.
