这里的id 可不是指 ID card，而是 identify（辨别身分）的意思。
Id 作动词用时的时态和形态变化有：ID'd or IDed or ID'ed, ID'ing or ID·ing。
3. Blind spot
这里指"A part of an area that cannot be directly observed under existing circumstances盲区"。
Blind spot 还可以指"Subject about which one is ignorant or biased某人一无所知或是抱有偏见的事物"，例如：The boss has a blind spot about Henry; he wouldn't fire him for anything.
4. We had two hour's notice. Two hours, what the fuck do you think this is, NASA?
这句话的意思是 The police didn't have very much notice to set up their video equipment, which is why they have a blind spot. NASA （美国国家航空航天局）has very good technology. Cop2's comment is referring to the fact that their equipment was put up quickly (in only 2 hours) and that they have poor equipment.
