Threat assessments are done before the operations, if it is considered to be a fortified objective it will not be entered, thats why they developed and deployed shoulder fired Thermobaric explosives weapons, after all the target was known for anti-gov terrorists sympathy booby trap bomb making, plenty of proof in this thread alone to get a jury to convict.

The thermobaric has been battle tested in Afghanistan and tested against large city building in the U.S. and deployed to some federal agencies, it is only a matter of time before they become common in use against fortified position domestically.

Best defense is a good offense
