I mean, thanks for the link I guess, but I'd say this sentence leaves out some very important details. Namely, that the cops are claiming that this person shot and seriously wounded a cop first.
To be clear, your linked article explains how it's not really clear yet what the sequence of events were, or if the person actually shot a cop. But I'd put it like this:
1. If the person did shoot the cop first, I have no problems with the other cops opening fire.
2. If the person did not shoot the cop first, then the cops should face severe legal charges.
Since the facts on the ground are not yet known, I'll withhold judgment.
