Corrected entry: When Desmond Elden is shot in the head in the garage of the ballpark, the SWAT member pulls the charging handle of the rifle which wastes a round that hasn't been used. Even if he ran out of ammo he would not have to pull the charging handle but simply slap the bolt release on the side of the rifle after changing magazines.

Correction: Not necessarily. It's entirely possible that the rifle jammed and the trooper pulled the charging handle to clear it. Unless you can see from the side that the bolt is open or closed, this mistake can't be confirmed.
