No Creditable Threat

Yeah, Right.  There was no threat, creditable or otherwise,  before San Bernardino.  I figure ISIS will try that again, just as soon as they can find the shooters to do it. The San Brnardino shooters were unusual in that they gave no warning, aroused no suspicion of them selves before they struck, and were willing to give up their lives for their cause.  You don't find shooters like that just everyday.  But I figure ISIS will come up with some and send them out to kill, any day now.  
   Hold onto your hats, the party is gonna get rough.
