Law enforcement officials predict at least a few Iowans will make a show of carrying their handguns openly in public and challenge anyone who tries to stop them when a new weapons permit law kicks in Saturday.
. . .
Iowans for years have been able to tote a gun visibly while in public, as long as they had a valid "permit to carry." However, sheriffs often wrote notes on permits saying the gun owner had to keep the gun concealed, or couldn't carry while drinking alcohol, or setting other limitations.
Under the new law, sheriffs can no longer place any restrictions on permits, and some believe this will embolden a few gun owners to carry their weapons more flagrantly.
