I am curious to know if the FBI ever prevented a crime if the person of interest was going to do it or do they just watch.
Depends on what the motives and targets are.
The feebs not only watch but facilitate.
People are denied all the time with a NICS check, for a variety of reasons. They want to disarm us while surrounding themselves with guns just like those dudes in white in The Hunger Games.
Here we have Al Issa. Someone on the Feebies radar for whatever reason and not a thing happens during his NICS check.
Some folks have done some research and found that the neighborhood the supermarket is in has a large Jewish population. So, some postulate that is why the Muslim chose the King Sooper.
Aside from the large Jewish population, the politics of Boulder is extremely Left and they are rabid anti-gun. Ergo, the folks in the King Sooper were defenseless and he knew that.
So, after all of that, I’m pretty confident a quick visit from law enforcement, either the Feebies or the locals, could have prevented this. He probably would have sh*t his pants when they confronted him. Especially if they had done it on the street. If he cried that they were profiling, a simple rundown of his ISIS sympathies and affiliations would put that to rest.
NO! They take innocent people like Richard Jewell, ruin his life wrongly. They trade information with a scumbag mobster “whitey bulger” that caused people to lose their lives. They shoot Randy Weaver’s wife in the back while she is unarmed and holding her baby. Ohhhh.... these are all “PROUD” days for the fbi. They only thing they “PREVENT” is you doing “ANYTHING” The left does not approve of. They are an armed tool of the leftists and democrats. frank marshall davis jr filled it with a bunch of minority-hires, as opposed to the best and the brightest. Remember that the next time some fed gov thug confronts you.
