Trusted law enforcement contacts who were on the ground during the Los Angeles riots shared detailed observations based on their firsthand experience. They requested that this information be disseminated to officers nationwide to support preparation for future demonstrations.

Their assessment indicates that many demonstrators were highly organized, with certain groups deliberately working to escalate peaceful protests into violent confrontations. The following observations are provided to assist officers and team leaders in developing effective operational responses.

1. Infiltration of peaceful demonstrations

Several groups were identified as allegedly inserting members into peaceful protests to provoke violence. These included:

  • Antifa – Dressed in all black (“black bloc”) with red or yellow scarves and masks
  • Trantifa – Similar black attire, but with pastel-colored scarves
  • Brown Berets – A Chicano nationalist paramilitary organization; a suspected member, Alejandro Theodoro Orellana, was reportedly arrested by the FBI for distributing military-grade face masks to rioters
  • Anarcho-socialists

2. Signs of pre-planned training and coordination

Observers noted that violent demonstrators used similar tactics and formations, suggesting prior training and organization. Their behavior did not appear spontaneous.

3. Use of recon scouts and encrypted communications

Antifa scouts were seen riding black e-bikes and e-scooters, reconning police positions from the front and rear. These scouts used encrypted communications and marked their vehicles with a white “X.” Be cautious, because it appeared they were organizing flanking movements to be made on the police lines.

4. Multi-layered skirmish lines

Violent demonstrators are consistently using multi-layered skirmish lines. These formations can envelop and cut off insertion teams, including tactics like the crossbow. The front line acts as cover, allowing individuals in the second and third lines to launch ranged items — such as poles, rocks and bottles— while remaining protected.

In two observed instances, second-line skirmishers were seen using 3-gallon garden sprayers filled with paint, oil and silica sand to disable visors and Lexan shields.

Officer tip: Use sacrificial lenses on shields and intercept these individuals early.

5. Skateboards as dual-purpose tools

Initially used for mobility, skateboards were later deployed to:

  • Smash windows
  • Act as improvised weapons

6. Legal observers on the frontline

Protest groups positioned legal observers toward the front, wearing high-visibility vests and helmets, equipped with cameras to document law enforcement actions.

7. Vehicle-based disruption

Some vehicles were reportedly driven to deliberately disrupt police lines, causing confusion and separation among officers.

8. Delivery of riot gear

Observers reported trucks delivering riot protective gear directly to demonstrators on site.

9. Use of fire as a weapon

Fire was used as a tool of destruction:

  • Vehicles, including Waymo cars, were set ablaze
  • Two individuals were arrested for throwing Molotov cocktails at officers

Final thoughts

Officers responding to civil unrest must be:

  • Properly equipped
  • Well-trained in team tactics and arrest procedures
  • Prepared to distinguish between peaceful demonstrators and violent agitators

A final word of caution: “There is a dedicated anarchist out there, who has trained hard to acquire the skills to seriously hurt you physically, legally and emotionally. He is prepared for you. Are you prepared for him?”

Prepare.
