Bismarck police say they're prepared if an active shooter situation should arise.
Six people in the U.S. have died from those kind of shootings this month, including four service members at a military recruitment center in Chattanooga, Tenn., two weeks ago.
Last week, a man gunned down two people and wounded others inside a Lafayette, La., movie theater.
Police in Bismarck say officers are trained yearly to prepare for many types of dangerous situations.
"I think years ago, I think we've learned from these cases that it's a lot of pandemonium and chaos. Often we have multiple jurisdictions involved, different radio frequencies, that type of thing where communication is very difficult. That's why it's important to train," said Sgt. Mark Buschena, Bismarck Police Department.
The department can't go into detail about specific plans for safety reasons, but the goals are to remove people from harm and to isolate and contain the shooter.
