This is actually a concern for crowd control. Look up articles about old time street riots, like the Civil War Draft Riots, and you will find mentions [0] of crowds armed with "brick bats":

> At 4 P.M. on July 13, "the children numbering 233, were quietly seated in their school rooms, playing in the nursery, or reclining on a sick bed in the Hospital when an infuriated mob, consisting of several thousand men, women and children, armed with clubs, /brick bats/ etc. advanced upon the Institution."

"brick bats" means chunks of paver stones and bricks, typically pried out of the street, used as improvised projectiles.
