Different categories of diplomatic/consular staff have different levels of diplomatic immunity. Here's a complicated chart that details some of that: https://www.state.gov/m/ds/c9127.htm https://www.state.gov/m/ds/c9127.htm Note in particular that rather a lot of categories allow the offender to be detained or arrested, and to be prosecuted if their actions were not "official acts". (And if "beat up those protesters" were formally affirmed as an official act, I suspect that would have more serious consequences than just prosecuting a few security staff members. Assuming the current administration didn't just give Erdogan a high five, anyway.)
