It depends on the state.
A local grand jury declined Wednesday to indict Henry Goedrich Magee for the Dec. 19 death of Burleson County Sgt. Adam Sowders, who was part of a group of investigators executing a search warrant for Magee's rural home.
Sowders and other officers entered the home about 90 miles northwest of Houston without knocking just before 6 a.m. Authorities were looking for guns and marijuana.
Magee's attorney, Dick DeGuerin, said his client thought he was being burglarized, reached for a gun and opened fire.
Juries often reflect the viewpoints of the population at large and my guess in Texas they are getting sick and tired of using no knock warranties to bust non violent offenders just so sheriff boys get to play soldier using military weapons, gear, and tactics. The jury was sending a message to judges and prosecutors. If you order a no knock warrant and get someone killed the blood is on your hands.
