The media focuses on violence and crime, because that's what media does — "if it bleeds, it ledes" — but that violence/property damage/theft has not been connected to the large Cap Hill/downtown protests for most of the week.
Your claim of "dozens of cars burning in the street" is, as far as I know, completely unfounded. As is "busting through every retailer's window and looting stores until they were bare." There isn't all that much retail downtown — do you mean Westlake?
There was some looting and some police cars burned on the first weekend, but it is important to understand (1) that these actions do not reflect the majority of protesters and (2) the history of violence perpetrated by SPD against citizens and especially citizens of color.
It is also important to understand that the SPD has responded to peaceful protest with violence every evening, through at least June 2. (I have not yet caught up with last night's protests.)
