I don't know if he should have been suspended indefinitely, but certainly an assessment of his self control considering he elbow'd the guy for no reason.
We also don't know the locations crime rate, if guns are prevalent, what the conditions are ... anything. The cop could have been in a seedy neighborhood where a cop was shot last night and this guy is a suspect. We don't know enough information to pass judgement on an internet forum.
Let's also not forget that the kid was clearly resisting arrest. That never goes down well. Excessive language? Yes. Antagonizing the suspect? Yes. Cause of indefinite suspension? Not in my opinion. These behaviors can be corrected with proper training, and if not, let him go.
