You think this is legal??

It was standard operating procedure. Suspect in bombing in neighborhood? Check. Considered armed and dangerous? Check. Need to clear neighborhood of private homes while maintaining the safety of the citizens and the LEOs. This particular house looks like it was inhabited by young adults, maybe college students? I did not see young children, as you would have seen if it were a family. So let's assume it was a bunch of "kids" who were renting that property... They're trapped at home, maybe partying, maybe shacking up, who knows? The team is charged with clearing the house, room by room. Primary pat downs inside are general and incomplete, due to lack of room. They are flushed outside for a more thorough pat down, and must be considered as dangerous until this is completed. That process is by the book, and has cost lives in the past when not followed. Operators are not allowed to make a judgment call on this in the field. All was done in the name of public safety and that area of the Commonwealth was under an emergency order. Not martial law. How would you feel about it if it were your kid, brother, father on that entry team?
Between this and the call about Miranda, the ACLU and others can go eff themselves in another country. As far as saying it must be tens of thousands to be considered a WMD, I won't even dignify that with a reply.... You would be surprised what was discovered in different house searches that was unrelated to this particular operation. You haven't seen public mention of those being prosecuted due to those discoveries not being in the scope of the search. (They will prosecute the guys found to have a pipebomb in their car, though.)
