It depends on the mall, but the nearest 80s-style enclosed mall to me has quite a few vacancies in it.  The parking lot has tumbleweeds blowing across it, and they don&#x27;t even grow here.<p>And on the other side of the equation, American cops are trigger happy, their SWAT-team-equivalents are swimming in drug war forfeiture slush, combined with military surplus purchase programs, and the citizenry itself has a decent quantity of concealed pistol carriers.<p>Shooters on foot could kill a lot of people in that first 30 minutes, but after that, the easy targets are all gone, and the retaliation force is on its way to &quot;arrest&quot; your shooters.  It doesn&#x27;t take all afternoon to [opportunistically grab some unpaid merchandise and] scramble for the exits.<p>Making Americans fear <i>shopping malls</i> is a tactical wrong move.  We have already turned against them, mostly.  You have to know the culture better.  You have to make us fear our own cars and roads.  If we stop driving on a daily basis, the whole country collapses.<p>But with over 30k highway deaths per year occurring already, in the absence of any malice, that&#x27;s a steep uphill battle.  It&#x27;d be like putting additional poisons in a carton of tobacco cigarettes.
