The police can only stop someone if they see that person committing a crime in their presence or for probable cause. California has no law requiring a front license plate. The officer appears to have had no right to stop you. That is why he asked for permission to look in the truck bed. If he had found anything illegal, his finding could probably be barred from being presented as evidence because the stop was illegal [fruit of the poisoned tree; since the stop was illegal, the search, even with your permission, would be illegal.
