Excessive force supported by the military?

I begin with what has happened fairly recent. The Merced hookah lounge incident. With it's star of the hour, Joseph Opinski, served for the United States military, who, keep in mind, was cleared on multiple shootings here in Merced. Son to Greg Opinski, a construction contractor who's caught in a political scandal with former mayor Tommy Jones on bribery. 

There was far more better ways to have served the warrants. For instance, they could have avoided any conflict with the people by watching and observing in casual clothing. Later, waiting for the best time to arrests the suspects. Preferably in the best interests of the public. Yet they did it by brute force, possibly knowing it would cause conflict with outsiders.

Given Joseph's history with the Merced Police Department as well as others. Does the US military look the other way or even support the negligence of Merced county's intelligence? Especially when they served towards their interests...
