Can a police officer search me or my car for no reason?
警察可以无缘无故搜查我或我的车吗？
No. There must be a reasonable suspicion that you committed a crime or you are under arrest, or an inventory search is being carried out prior to a car being towed to allow a police officer search. If the search is illegal, any evidence may be suppressed. However, you could still be convicted on other evidence.
不可以。必须合理怀疑您犯了罪或被捕，或在拖车以允许警察搜查之前正在进行库存搜查。如果搜查是非法的，任何证据都可能被压制。但是，您仍然可能因其他证据而被定罪。
