...they rely on the FBI or Secret Service Local, County and /or State Law Enforcement. <<
Prior to 1934, the FBI wasn't authorized to carry guns and had to rely on local cops and sheriffs if they needed to arrest somebody dangerous.
It would be best if "federal law enforcement" were limited to .38 snubby revolvers, and required to get local sheriff's backup. With local sheriff having the option of saying "no".
Yep...
Although I’d be more generous... I’ll let them carry a Glock or even a 1911, for their own protection.
