Just read some responses to the NRA call for staffing schools in the local news paper.... and it's interesting that the SPLIT is so obvious - the elected officials think guarding the schools is a ridiculous idea - and they clamor for gun bans... but every police department (except one) thought it was a good idea and already had "SRO's" (School Resource Officers) in place. There was - of course - the question of cost and who pays. That is a natural consideration. Thus my earlier proposal to tax guns and ammo etc heavily. 
King County Sheriffs Dept. --- the largest population base in the state --- has been having budget issues for YEARS...
