Cheekin' and Peekin'
An advanced method of "slicing the pie," a tactical method of maneuvering & positioning oneself while firing a weapon from behind cover. This is a method that is not used by many law enforcement agencies, as is it far too advanced for most officers who only have basic firearms training.
"Officer Bell was cheekin' and peekin' from behind the mailbox as he fired his Glock 19 to terminate the threat in the firearms confrontation."
