7-10mg/kg will cause unconsciousness, and is dangerous without CLOSE airway monitoring.
Just barely dangerous. You might see a bit of transient respiratory depression, but the risk of respiratory arrest or clinically significant hypoxia is very low even in an out-of-hospital setting. We have case reports of paediatric patients receiving as much as 50mg/kg without significant ill effect.

I think perhaps you assume empty stomach, such as in a normal setting. Those doses are puke probability 1.0 range, which is lifethreatening if the person is unconscious and unmonitored.
Ketamine doesn’t really depress respiration that much. If the airway is physically obstructed, however, because nobody had their eye on him...

It's probably quite dangerous in this kind of setting though, where the person has likely already been beaten, tasered and choked.

My goodness that's a lot of ketamine.
A "strong" recreational dose would be about 1mg/kg. 2.5mg/kg and the person is anesthetized.
Obviously it's more than he should have been given (and tbh am pretty uncomfortable with it being given here at all), but my decidedly non-expert opinion (and the official autopsy statement that the "ketamine in McClain's blood was at 'tolerable levels' ") is that there's all sorts of red flags about this situation.
