Exercise

Counting protective frisks

During a vehicle search, the police officer may pat down the driver to check if they have a weapon. This is known as a "protective frisk."

In this exercise, you'll first check to see how many times "Protective Frisk" was the only search type. Then, you'll use a string method to locate all instances in which the driver was frisked.
