Uh, don't they need probable cause to run you through the "system?" Or are we all suspects of something now?
This is a violation of the National Crime Information Center (NCIC) policy. They have no business using this for such a fishing expedition.
A formal complaint needs to be raised, and escalated through a Congressional representative, demanding an NCIC audit of the use of the system by the WMPD. They should lose their access to the system.
And, oh yeah, sue them.
