Driving around in hopes of witnessing agents jumping out of trucks and detaining immigrants has become a grim pastime and form of protest for some Angelenos.

US Marines in Los Angeles detained a civilian amid protests over Trump's military parade, marking an unusual military involvement in domestic issues.

Armed Marines have taken to the streets of Los Angeles as part of a controversial deployment ordered by Donald Trump, raising tensions ahead of mass protests against his administration's policies on immigration.

LA County District Attorney Nathan Hochman noted that combing through social media posts and other available videos will also assist in identifying those who committed crimes during any of the protests,

A 27-year-old Army veteran was briefly detained at the Wilshire federal building shortly after Marines arrived there.

The SLO County responders are being sent for public safety purposes and to protect government buildings, the release said. They will not be assisting with immigration enforcement.

Protests against the Trump Administration’s immigration policies, first ignited in L.A., have spread across the country.
