Why do Depp defenders keep mentioning the LAPD bodycam footage as a smoking gun?

I still hear people talk about the 4 officers and released bodycam footage as proof Amber lied - that she had no injuries and the place wasn't destroyed.

However, we hear on a call with Johnny after the fact (I believe AH didn't know he was recording) that Amber insisted she was not the one to call the cops and she didn't talk to them because she wanted to protect Johnny.

The bodycam footage backs that up - the cops come in hours after JD left and the group had time to clean. The cop doesn't get any closer to Heard than 10 ft (and testified that her face lookeda little red). Amber nor her friends say much and the officer leaves after 30 seconds.

It seems like defenders like to bring this up because having law enforcement involved seems legit, but then when you watch their testimonies and footage, it tells us exactly what Amber said.
