Or maybe they are just old enough to remember when one could call the police for assistance without worrying about the whole place getting all shot up.
The big change happened in the 1970s, when using the excuse of some police assassinations, the federal government encouraged police nationwide to discontinue using “Old West rules”, and adopt “SWAT rules”.
This means things like, assume ambush at traffic stops, brandish gun frequently, it is essential to assert control in all situations ASAP, etc. The end result is more cops getting killed, often with their own guns.
