RCW 9.41.270,
"It shall be unlawful for any person to carry, exhibit, display, or draw any firearm . . . in a manner, under circumstances, and at a time and place that either manifests an intent to intimidate another or that warrants alarm for the safety of other persons."
I figure the police simply wanted to give them a break and not charge them.
How do you know if they were intimidating anybody? I didn't read that anywhere. How do you know they didn't take them for self defense?
