1. 3 Shop owner killed alleged looter / passerby
2. 4 Killed by police
3. 8 Killed by protesters/rioters/looters
4. 5 Other deaths
And that is assuming all of the looters are part of the protests, when in fact at least 2-3 of the deaths in category 3 could also be black protesters targeted by radicals, or simply robberies happening around the actual protests.
In the meantime, there are 25 separate police violence incidents on the same wiki page, with another 50 against journalists collected by a journalist. The same page reports 7 incidents of violence against the police and 4 against non-police.
So I believe my point stands. Not to mention that the police should always be held at a higher standard of conduct and respect for the law than random people.
