Yes, and it will get tighter and tighter every day.
Remember, tight security stops you doing things and you get watched more. Tighter security stops you doing more things and you get watched even more.
So, eventually, you won't be able to do much without failing a security check or without being watched.
Do you like that?
That's what happens when security behaves like everyone is a potential terrorist (guys, Grandma is not a terrorist OK?).
