An interesting info source is a site called leoaffairs.com and it is a place for police to go and chat.

The forum thread for Broward County about the SRO is interesting. Some are insisting that some may have been ordered to hold back and form a perimeter, some are calling for the radio records to be realeased. Some posts describe the school as a place where there are many mentally ill children dumped there. I figured I would post it because each state has a section. As things happen it may be worth it to check out their chatter.
