LOTS of Military police in town

We just walked into town for dinner from Playa La Madera and noticed 5 large military convoy trucks parked where the buses usually park by the canal. Is this normal for the weekends lately or did something happen?. We were on Cinco de Mayo and saw a lot of military driving by also heading toward the pier. I know I have read that they have been sending more into town but hadn't seen any real presence this week so far. Just curious. Thanks for any insight. By the way, have a wonderful time here relaxing, eating, wandering, swimming and enjoying our home away from home! So good, as always to be back.
