You can’t be THAT stupid. Suggest you put the shovel down.
Trigger locks and gun safes will ABSOLUTELY prevent someone intent on murder from using the guns on which those locks are applied or that are stored in those safes. That’s why they are sold and used.
Yeah, it really is THAT simple.
"Those guns", but trigger locks and gun safes ABSOLUTELY won't prevent a premeditated murderer intent on mayhem.....unless of course you have a way of making it mandatory for everyone including gangbangers, drug dealers and street criminals. Oh wait, those people just don't GAS, do they?
