Don't forget federal Inter-op freqs.
The Federal Bureau of Investigation is an agency that conducts sensitive investigations, at the state and local level, and also espionage and terrorist activity.
They go against the low life scum, as well as criminals whom are educated : both blue and white collar professionals.
They are not the border patrol, the U.S Marshals ( even the 1811's ). They are an investigative agency, whom under the Department of Justice , most generally have to get permission from the Attorney Generals office, or an Assistant U.S Attorney, unlike some other federal agencys whom just ask their boss if it is oh-kay.
Same with the U.S Secret Service, and next to the Diplomatic Security Service is one of the best, in my opinion, Federal Law Enforcement agencys. The Security Clearances of FBI, DSS and Secret Service Agents is very high, and a background check is thorough. TS/SBI's do not come easy, and are not handed out like candy.
Radio communications of Federal Agents of this sort has to be secure, because of not only the safeguard of activity, but work essential to national security , such as terrorism, espionage, spys. Careful planing of the radio spectrum, power level, location and transmissionis all based on good COMSEC ( Communications Security ) work. I would expect secure cells to be used, as a VHF, UHF radio can be picked up, even though it cannot be heard. " Hey......407 MHZ, and 163 MHZ. Some feds are running around here somewhere." It don't take a genius to pick up a radio freq on a frequency counter, or " Close Call" to know that some feds are running aorund in your A.O ( Area of operations ). Adjust the squelch, and you have an idea of how far they are away.
I keep seing threads upon threads of "US Marshals" and "FBI" and "Border Patrol". They want their comms secure for a reason , and that is their safety and maybe their lives depend on it. Border Patrol cannot be chasing drug or human smugglers, if the bad guys can tune into the Border Patrol and know their location, strength, assets and other pertenant information. And in some cases, it could very well likely wind up in Border Patrol agents getting ambushed with rifle / machine gun fire. Criminals killing agents, cause they do not want to go to jail for 40 years, due to they have a large amount of dope. A person committing criminal activity, whom faces many charges if caught and about 30-50 years incarceration ( ex= drug possession, transporting drugs across state lines, firearms in commission of a felony, possesion with intent to distribute, drug trafficking ) does not loose nothing ( in my opinion ) by killing a Law Enforcement officer(s).
The Federal Bureau of Investigation is the investigative arm of the U.S Government, and the only agency whom is chartered, and can by law, can perform intelligence activity in the U.S. Now other agencys can, and have the capability, but legally, the FBI is the only agency that is allowed. I guess the CIA, NSA and others could perform work in the U.S , and pass that info to the FBI, but if they were caught...Congress would have a fit ; heads would roll on the hill, agency administrators fired, and investigated for criminal charges. A civilian could illegally use audio and video surveillance for their own knowledge, but if they were caught...They could face tort and criminal repercussions. Illegal surveillance only comes with repercussions if you are caught, but sometimes it can contain a wealth of information and be beneficial. Use it wrong, or others find out ----- > They will have to "Pay the Piper."
If the U.S Government wants you know what they are doing ( with all due respect ) , they will put it in the paper, or on TV, or both.
