As for what I want to happen. I am certainly not going to just throw up my hands and hope this won't happen again because- that is the exact way to make sure it will happen again. If you want different results, you have to try different methods.
I expect, when law enforcement officials are "questioning" a suspect (as they questioned this guy) that they actually do a thorough job of questioning (free of politics and pc nonsense) and make sure he is innocent before they release him/ her.
It seems that in almost all of these cases, these terrorists are questioned by law enforcement then let go. It happened in this case, in Ft. Hood and in the orlando shooting. It happened in others as well, I just don't feel like going to look them up.
There is obviously some disconnect in which these people are let go. We need to fix that, immediately.
Also, during the Obama administration, Obama wanted to treat this a a "law enforcement" issue, but its not. Its not at all (can't even imagine what he was smoking on that one). They are enemy fighters. Maybe "law enforcement" shouldn't be handling the questioning. Maybe they should be brought to a military facility and the military should "question" them.
