I guess I.S.I.S. Terrorists know police system very well.
TERRORISM of Paris this time isn't simple.
Terrorists know a lot of things about France, Paris, police system and government system.
Terrorists made a plan seriously.
And a lot of French cooperators existed absolutely.
May be I.S.I.S. members know the secrets of France.
French Government must make measure immediately.
Let me say again.
Terrorists know the police system of France.
