“No, not when multiple countries are warning the government about these foreign Muslims not to mention they were on watch lists. In fact there have been multiple arrests of these people and family members for various previous crimes.”
I think you misunderstood me. I don’t mean that it’s difficult to pinpoint which ones to infiltrate. Even if you know someone is probably up to no good, how do you “infiltrate” an individual, or someone who only conspires with a family members and trusted friends?
The feds can infiltrate groups, because groups recruit new members with some regularity. People don’t recruit new family members or friends the same way.
In fact, the U.S. had so much knowledge of these people and their activities, I am suspect they just allowed those at the marathon to be blown away...What the government's motive for this was, is anyone's guess.
