Some Wisconsin bars requiring valid driver's license or passport

Just something to file away. From Madison, Wisconsin:

Some Downtown bars now only let in patrons who have a current, valid driver's license or U.S. passport, a policy bar owners say has significantly helped improve security after a spike in violence that hit the region over the summer.
"It really helps with curbing incidents in your bar," said Jimmy Hahn, who's worked crowd control for several Downtown bars for decades.
He defended the policy against some patrons turned away who claim it unfairly bars racial minorities from entry.
"It's not racist," he said. "I turn away every race that has a (state) ID card."
State-issued IDs, as well as those issued by colleges or other entities, don't cut it for entry. . . .
Jay Wanserski, who owns Wando's, 602 University Ave., said he put the policy in place shortly after a July incident during which four of his bouncers were hospitalized when a large group of people attacked them outside the bar, the latest in what some described as an unusually violent summer Downtown. . . .
