I think it'll be awhile before the police catch him; he seems pretty good at E & E. If average folks in that area regularly carried concealed weapons, though, it wouldn't be too long until an armed citizen came across him either setting up a shot or exfiltrating after making one. Especially this one I hear about where he voluntarily confined himself to a shopping-center parking lot that he could easily have been blocked into...but wasn't, because there weren't any police in the area.
Criminals almost never commit crimes around police, which means the only folks who are ever going to be able to stop them are armed citizens. Police are for filling out forms, tying on toe tags, and performing investigations, not for preventing crime or protecting people.
