Police have shot and killed Maurice Clemmons, the man suspected of killing four police officers in a coffee shop in Parkland, Wash., officials say. A spokesman for the Pierce County sheriff's office said that Clemmons was found walking in a Seattle neighborhood slightly before 3 a.m. and was shot after confronting police.  Clemmons had been on the lam since the shooting Sunday, and police believe that he was assisted by family members. Clemmons' sister has been in police custody since late last night. Meanwhile, there's more chatter that Mike Huckabee's decision to commute Clemmons' 108-year sentence when he was governor of Arkansas might prematurely end any presidential aspirations he might have had for 2012. Huckabee's commutations during his time as governor were an issue during the 2008 campaign, largely because of a convicted rapist who murdered and raped again after he was freed. "People might be able to understand one instance," a GOP strategist tells the Los Angeles Times . "But now you have two different episodes where he's shown poor judgment."
