I am somewhat surprised that the city is not blaming the gun range for the lead contamination in every body of water in the city.
Some games do in fact request Administrator rights when run from Steam on every launch. Typically, this is a consequence of a bugged launch condition check that fails to accurately detect that needed libraries are often installed; choosing not to authenticate will still allow those games to run properly, and workarounds exist to eliminate the incorrect detection entirely.
The term "assault weapon" is a nebulous term based upon the presence of features that do not affect actual firearm function. Most "assault weapons" are in fact civilian sporting rifles featuring a pistol grip and at least one other defining feature that are most commonly seen at target ranges and occasionally in the hands of hunters.
The term is applied for the specific purpose of confusing those unfamiliar with firearms into believing that common civilian sporting firearms are actually military weapons.
