We do it all. 
...not to mention, we are the only feds that can just go "freelancing". I don't know anyone else that can have another cop/agent walk up to them and say, "Hey, do you want to go arrest this guy?" and then go out there and just do it... no UFAP, no requests for permission or letters of authority, etc.
We bring evil things to evil people, kicking in a door near you!

in practice, there is."

"The difference between 'involvement' and 'commitment' is like
an eggs-and-ham breakfast: the chicken was 'involved' - the pig
was'committed'."
