mike如何知道他们是警察？
mike在进酒店时，看到：1. bellhop （宾馆服务员）都带着白手套；2. 酒店泳池今天关闭（视频1'43"），  
而当他走近房间时，1. 看到bellhop没有带白手套；2. bellhop说泳池正常开放； 3. 问时间时西装男露出了配枪。  
但是，后面harvey问他如何知道他们是警察，mike回答是：i read this novel in elementary school, um, cops were staking out a hotel （监视酒店）. one of them dresses as a bellhop. the other is a man in a suit. and it was the exact same thing.  
mike的回答并没有提及“白手套”和“泳池关闭”，逻辑上存在一些瑕疵。
uh, throw them off. i mean, what kind of drug dealer asks a cop what time it is when he’s got a briefcase full of pot, right?  
throw them off - 障眼法；转移注意力; to misdirect someone away from the subject of their pursuit; to steer someone's investigation or suspicions in the wrong direction. a noun or pronoun can be used between "throw" and "off."
