Hmm... as someone who lives in LA... I think your news stream is polluted. There were maybe 100 bad actors. Responding to people in military gear vanishing day labourers and fruit sellers and seamstresses. Bringing in 10,000 National Guard and 1,000 Marines is not an appropriate response.
50 people raiding a Nike store in LA isn't even beyond local news lol... you can find hundreds of videos online of this happening on a regular basis for the past decade.
If local police are unable or unwilling to protect federal agents doing their jobs, bringing in the military is absolutely the right decision. These rioters used hammers to destroy concrete bollards, pelted federal agents with the fragments, and faced no resistance from the LAPD while doing it.
