Prepare for increased violence on the streets and attacks on police.
Malcontents and agent provocateurs may take advantage of the anger and chaos to pursue their own agendas of retribution and anarchy to commit acts of violence. We have already seen a false narrative of Metro/National Guard shooting unarmed persons. Uncritical segments of society will take the shootings as police declaring war on protesters. Do not be surprised if we see targeted police assassination attempts in low-impact areas.
Prepare for a curfew.
If violence and rioting continues, don't be surprised if the city of Las Vegas, Clark County, or other cities declare a curfew. While this will not be strictly enforced, it will lead to a lot of people leaving the streets and businesses closing.
As the casinos re-open, expect a more resolved approach from police.
Nevada's economy has been devastated by the lost of gaming/tourist revenue. It is vital that we re-open the casinos. Metro will probably draw a harsh line over protests on the Strip/Downtown that affect re-opening (which could spur increased resistance). Do not be surprised if there is little tourist traffic or casinos delay re-opening. Also do not be surprised if bad actors actively attempt to stop casinos from re-opening.
Expect a lower police presence in some neighborhoods.
Police will likely be pulled from all areas of Southern Nevada under mutual aid. Your area may have fewer officers on patrol and non-urgent calls for service may be delayed or not responded to. Aggressive/proactive policing may retract as officers feel they are in danger, under siege, or hated by the community.
Be prepared for random looting/robbery/burglaries away from protest areas.
If police are busy with a riot elsewhere, criminals may take advantage of long police response times or little/no presence to target places for crime. We have seem in LA and New York protests being organized in areas with high-end shopping that have quickly devolved into looting sprees. Some Walmarts in Nevada have closed and barricaded their entrances.
Expect racial tension/violence to rise.
Most people are good people who see the character of each person regardless of race, but there are a lot of idiots out there who can only see skin color. Unfortunately race becomes a uniform of sorts when people become tribal. Violent racists on any side may use these events as an excuse to turn their hate into action.
Traffic problems may magnify.
Pop-up protests may close freeways, trapping motorists inside of protests and riots. At any moment, a "peaceful" protest on a freeway could turn ugly if a vehicle/pedestrian collision occurs (get a dash cam). Stay away from areas of unrest. Know alternative routes and take them. Pay attention to news and traffic if you must go through potential unrest areas. Be ready for police roadblocks as well. Public transport may not be available.
A second wave of COVID-19 is inevitable.
10 Minnesota National Guardsmen have tested positive for the coronavirus. So many people in very close proximity; shoulder-to-shoulder, yelling and chanting, is spewing the virus everywhere. Even though many are wearing masks, many aren't. Masks have also been shown to be at best only a litigant against infection. Lock down orders will likely be ignored by the masses.
Don't be surprised if organized attacks/bombings take place.
Use of improvised explosive devices are common in uprisings around the world. Political bombings (and against police) are not unknown in American history.
