I have been an Army medic for 7 years and get a chance to occasionally work in ERs and do ride-alongs with ambulance/FD crews when stateside, so here's my 2 cents on this and a couple of other med issues...
- Skeptic Ginger is absolutely right, no paramedic is going to suture a laceration while on a call. First, it is unnecessary to stop bleeding, and secondly the ER doc is going to want to inspect the wound and have it irrigated prior to closure.
- Not all broken noses look like this:

or this:

Sometimes they look like this:

I had my own nose broken by a punch (boxing) and it only bled lightly, had no deviation, and was only slightly swollen. Picking it up on a surveillance video would have been difficult at best. It may be that GZ had an injury similar to this... or it may be that his lawyer is stating "broken nose" since it is difficult to disprove (most broken noses will not call for imagery, particularly if there is no deviation).
Likewise with the purported injury to the back of the head, a laceration can vary widely in severity. Lacerations of the scalp do tend to bleed heavily, even if the cut is shallow. A scalp laceration of the size claimed by the DC to be on the video would bleed significantly, IMO. There could also be some confusion on the part of the police officer who stated that he saw lacerations. Police officers are typically trained to a first-responder level which gives them very basic first aid skills. Terminology like "laceration", "abrasion", and "contusion" may become confused, particularly if there is blood obscuring the injury.
