You get the feeling part of the problem is "We're Feds,

we don't need your local crap." ?
The day before the attempted assassination of Donald Trump, a tactical team of local police officers set aside radios for their Secret Service partners so the two agencies could communicate during the former president’s July 13 campaign rally.

But those radios were never picked up.
I wonder if any of these people consider that the reason so many don't trust ANY of the federal agencies is said agencies threw the trust they formerly had away?
