I have lived in Los Angeles since the1940s.
1. I am glad that the police are not so heavy-handed as before. The civilians now have a little more control over the force.
2. I am not particularly elated that Mayor Garcetti may leave. As the Russians supposedly used to say: If you think that this czar is bad, just wait until you see the next one!
3. Regarding BLM, the African American population in this city is now estimated to be at 9%. Some of them are moving to other cities as Hispanic ladies & gentlemen move in. So BLM depends on the support of young Caucasian youths, who IMHO are making a big mistake in supporting that movement.
BOTTOM LINE: America is changing at a dizzying rate. All one can do is to adjust to the changes -- or move to another country. (There are as yet no flights to another planet,)
