1) Out all all individuals, how would we accurately identify the crazies prior to an attack?
Well, I'd hope that counselors, psychologists, etc. are trained to recognize someone who is a potential threat to themselves or others and report it to authorities/higher ups/fellow counselors (whoever). My girlfriend is studying to be a counselor...if they think someone is going to harm themselves or others, they have an exact procedure to follow. If someone is talking real crazy in a session, then they can commit them. The VT shooter had been in Virginia Tech's counseling services, it seems that people just didn't recognize the threat. This case seems to be a simple "miss" with a package sitting unopened in an office. Had someone opened it, I would have hoped they would have taken proper steps.

2) Once we think there is an identified crazy, who is responsible for cross-checking that assessment?
See above. There are procedures in place, people who should be notified, etc.

3) What do you do with the identified crazies? What about those that haven't broken any laws?
Commit them. Get them on medication. Put them on suicide watch. Inform their family. Inform the authorities (depending on how serious a threat you think they are). There are all sorts of things you can do if someone is talking to you and says something like "I've thought about shooting people" -- that's a red flag that should be taken quite seriously, and can be.

4) Do all 'crazies' present a risk to the public?
To a certain extent, most definitely. Some risks are more serious than others. There's a few homeless people around my office who are crazy. One guy is clearly schizophrenic, always yelling obscenities at someone who isn't there. Is he a "risk" to the public? Yes, he could flip out and attack someone, or run out into traffic, or any number of things. His risk is minimal compared to a crazy like this guy who wasn't homeless, had access to some sort of cash to get weapons, was smart/mentally capable enough to plan out an attack, and so on.
