My friends, that’s not obstruction of justice you can believe in:

A Democratic state representative in Alaska asked state troopers Wednesday to investigate possible witness tampering in a legislative investigation of Gov. Sarah Palin’s decision to fire the state’s public safety commissioner.

Since Palin became Sen. John McCain’s running mate, at least three witnesses have declined to cooperate despite receiving subpoenas in the investigation, Rep. Les Gara said Wednesday in a letter to the director of the Alaska State Troopers.

You might want to be less obvious about it next time.
