And you're taking the same mischaracterization that an above post takes: I do not feel this was okay because "these are nasty people", as if my delicate sensibilities cringe at the idea of "icky people", people that are different than me or have different view than I have.
That is a false representation of my views.
I think it's okay to roll up on these people because they think it's okay to blow up bridges, and because they took all necessary actions to indicate intent, which would clearly and unequivocally be a crime.
Due process? They will get their day in court. If it turns out that they were just minding their business, being upstanding citizens in our society until an FBI agent kidnapped them and forced them to participate in a bomb plot, then I will gladly eat crow and be on the side of their exoneration and justice.
I am sure there are many things our government does that would not stand up with respect to a hard, realistic look at constitutionality. I am not naive enough to believe that "because the government does it, it's not illegal" nor am I for the wrongful persecution of political or religious organizations "just because I don't like them".
But here is my bottom line: people that plot to blow up pieces of American infrastructure and who then take steps to follow out that plan are criminals. I'm kind of amazed I even have to state this.
