FBI UHF Channels

[Hooligan]

I strongly think that Government agencies such as FBI, CIA, etc, would use encrypted two way radio communications. They could also be using VOX based encrypted cell phones. Scanner people will never hear LE type traffic.

You don't deserve any respect after stating such an incredibly un-informed, feral opinion, wild (& uneducated) speculation, and broad, grossly erroneous statements like you did.

FBI SWAT Team & HRT Unit commanders are often seen in photos/videos with two radio antennas on their shoulders, and open-source material has suggested one radio is for intra-team comms, the other radio is for intra-team comms (a net/channel with command staff/tactical operations center, etc.). It'd make a lot of sense to minimize any interference or de-sense to critical comms ("Uh-oh, sorry, I thought you said 'Green Light!') by having a lot of RF isolation between the two, i.e. the assaulters on 413MHz, the talkers/suppporters on 167MHz, and the tactical commander up on both. It also makes sense as a commander protective over his or her tactical team to not have 'unnecessary' personnel listening-in, let-alone having the ability to accidently or deliberately tx on your channel during an event -- some jackass with a "test, test" or stuck PTT, let-alone some higher-up person outside of the chain of control trying to flex their muscles.

10 or 15 years ago, someone reported what they claimed to be FBI SWAT or HRT on a discrete 406-420MHz channel in the Detroit area after a K-9 was shot during a raid and a helo was requisitioned to take the dog to a vet.

It'd also make sense that at-least HRT and ideally, even the Division SWAT guys would have low probability of interception/low probability of detection voice comms gear available for certain high-threat situations.
