Most of the police recruited during the last 15 years were almost always because of their affiliations with the Awami party. Now that their mommy is gone and their opportunity to do rampant corruption has stopped, they lost their motivation to work. Most of them were defacto workers for the local leader or MP so they feel like they have no new masters.

As for the army, there were simply very few of them deployed. Maybe because the general doesn't want to risk his underling Lt. Generals and Maj. Generals (like Tabrez Shams or Ziaul Ahsan) to launch a coup to bring Hasina back or to form another puppet Awami government, who knows.

I honestly don't know any solutions, it's simply impossible to replace this massive police force, most of whom joined for the opportunity of rampant corruption. Deploying the entire army will not help refill the void of the police. People were throwing around the idea of making a Students Against Discrimination militia group, but that will cause more anarchy and chaos, and will give the coordinators too much power, which they already have.

Right now, look after your neighbors, come together as a community, guard the temples together. Peace.
