Dear PAO,
My brother was riding his motorcycle last night when he encountered a checkpoint at the corner of our street. He stopped as instructed, and the police officers asked for the certificate of registration and official receipt of the motorcycle. My brother, however, failed to produce them. Thereafter, the police officers asked my brother to open the tools compartment of his motorcycle to search for the abovementioned documents. Can the police officers legally ask my brother to open the tools compartment of his motorcycle even without a search warrant?
