Seniors, how close are we getting to becoming a police state?

Some schools now have security officers on duty now. Today's Pearls before Swine comic strip brings this to mind for the possible future.

The comic will not load here... only photos or videos can upload.
Update: May I add that our freedoms are very slowly and quietly slipping away. For instance minority now rules, not majority, being politically correct has gone way too far and we, the citizens are being frisked and embarrassed when traveling by air within our own boundaries.
Update 2: These are awesome answers and it's difficult to choose just one answer as best.
TD's are NOT from me.
