An officer is dispatched to a silent robbery alarm at a 24-hour convenience store. Upon arrival, the officer observes no unusual activity, and customers are entering and leaving the store. What is the most tactically sound initial action for the officer to take?
-
A
Park the patrol vehicle directly in front of the main entrance and use the PA system to call out the clerk.
-
B
Immediately enter the store to investigate, as the alarm is most likely false given the normal customer traffic.
-
C
Establish a covert observation position to watch the location and wait for backup to arrive before making an approach.
-
D
Disregard the call as a false alarm due to the presence of customers and resume patrol.
