Adam-12 S04E03 - The Grandmothers

A drug addict robs a store run by elderly women selling small items they make by sewing things such as pot holders and doilies. They spot a convertible with three men just after they are reported on the radio to have held up a store. A pursuit takes place and, together with Mac, arrest the three men. Later a nearby antique shop is held up by someone with a similar description to the first robber. He asked for a limited amount of money and a later call back to the first shop indicates he returned the money stolen earlier. A car is spotted making a rolling stop at a stop sign but the driver is a priest looking for the police to arrest a man from whom he bought marijuana. They accompany him back to the dealer's apartment and make the arrest. The final call is back to the first store where the same addict is in the midst of another robbery. They capture him followed by Malloy secretly buying some doilies after having teased Reed for buying pot holders the previous day from the "grandmothers".
