Terror cells activated in France?

French law enforcement officers have been told to erase their social media presence and to carry their weapons at all times because terror sleeper cells have been activated over the last 24 hours in the country, a French police source who attended a briefing Saturday told CNN terror analyst Samuel Laurent.

Hmmm.

World leaders are going to attend a rally in France to commemorate the incident and at the same time word goes out that terror cells have been activated?

Who is in charge of the President's security detail and how is this a good idea?

Spare me the "we must not bow to terrorism" jazz.  Appearances at social events or tweeting is NOT standing up to terrorism.  We saw the only real "stand" that takes place against terrorism when you saw RAID and GIGN storm the buildings where the terrorist were holed up.

The real question though is stark and simple.

How widespread is this and will we see attacks in the US, UK, Germany, the Netherlands or other parts of Europe?

Pass the popcorn.  This will not be fun to watch, but I don't think I can turn away.
