I've been following #poltwt this morning - a bunch of police forces around the globe live tweeting what is happening. It's pretty much been just routine stuff, PR puffery and the like. The closest thing to action was the ctrain crash here.
Then the LAPD tweeted they were on tactical alert due to a "major incident" at LAX
Apparently police shot a man with a high powered rifle and terminal 3 has been evacuated
