A leading Democrat says it would be “completely irresponsible” to let Wisconsinites carry concealed guns without safety training or background checks. State Senate Minority Leader Jennifer Shilling slammed a new G-O-P proposal to let people carry hidden firearms without the permits and training required when Wisconsin became the second to last state to approve concealed weapons in 2011 after years of rejections. Senate Republican Dave Craig of Big Bend and Assembly Republican Mary Felzkowski of Irma say people can already carry guns in the open without state controls — and the same should apply to hidden weapons. More than three dozen Republicans have signed onto their bill, which would also let parents carry weapons in their cars when dropping off and picking up school kids. The governor’s office says Scott Walker supports Second Amendment gun rights, but it did not say whether he favors the new bill.
