No "charge" bans you from owning a gun. A disorderly conduct conviction won't bar you from having a firearm, unless, as I understand it, it involved a "domestic" situation.
Downtown Milwaukee ought to be fun and interesting! Hey, it's just a Sig Sauer!
Madison Police told me recently that barring any obvious law breaking, their officers would [make that 'ought' to] simply observe unobtrusively to assure no law violations are occuring. I'd be pleasantly surprised to find that to be true of all LEOsin Madison, and shocked to find it to be true in Milwaukee. I think the chances of it being true in Madison are improving due to an effort to educate the department and its officers. They're aware that I haveOC'dand have not suggested that I discontinue the practice.
