because there shouldn't be any KA falses that are stationary (some exceptions maybe speed signs but those aren't as common) and most cops are switching to KA band which makes it a higher threat.

If you may have a KA false (frequency 33.6-33.7) it's a leaky radar detector near you...but those falses disappear once the car leaves the area. So there's no point for a lock out on those since they are moving falses.
