How is a reasonable number to be arrived at - are you fishing for something out of thin air? A guess? A pie-in-the-sky 'dreamland' nirvana where all crooks have been magically beamed off the planet? A statement that can be later used against me - what?
I don't think that you have a) any basis, whether empirical or theoretical, for a number either and b) DON'T have any clear or even foggy idea of just what the duties and functions are of these federal employees is on a daily basis, duties that keep an active and alive and ever-presnt criminal element at bay ...
To that end, I don't think you have *any* practical, real-life ideas about dang near anything save an oft displayed (but rarely vocalized) don't tread on me for any reason attitude; an antisocial attitude that is fine were you living on an island all by yourself where no demands are likely to be placed upon your time or assets ever ...
How many armed federal agents is enough?
One for each of us, of course.
How much of the federal government is coloring outside constitutional lines? Any of it?
Somewhere between 85 and 95%.
Are you happy with the ATF and its record?
Sure. I love writing letters to a friend in prison after being entrapped by them in a case that makes me sick every time I think of it. And that happily married family-man gun dealer in California really did commit suicide in his gun shop just because BATF agents walked into his shop, too. So did the kiddies in Waco, of course -- little bastards set the place on fire to make BATF look bad. And these reports of institutionalized perjury to get convictions are all really just a silly prank. None of this stuff is true, either.
How many FLEOs should be fired tomorrow in the process of returning us to a constitutional republic?
All of them. They need to be put through new training, taught quite a bit about the Constitution and their role as servants, have their oaths revisited with the Bill of Rights in mind -- and forced to re-apply from scratch. You could do it in stages -- 1,000 at a time, give or take. Of course several agencies have no authority to exist in the first place, so there'll be some good ole competition to see who passes the citizen-created litmus tests to get re-hired.
