I remember almost getting into the car and then seeing blue lights, and squad cars.

就当我要被塞进车里的时候，我看到了蓝色的灯光和警车。

Those squad cars need washing again.

那些警车需要好好洗洗。

That would be a " squad car." Here in Los Angeles, I don't know if it's still the case, but the squad cars are always black and white, and that's true in many American cities.

那将是一辆“警车” 。在洛杉矶，我不知道现在是否仍然如此， 但警车总是黑白相间的，在许多美国城市都是如此。
