The decision not to prosecute came despite President Donald Trump's vow that the US will not tolerate lawlessness and after extensive preparations were made for the caravan, including deployment of thousands of active-duty troops to the border. Charges were not filed because the administration generally doesn't separate families and because Customs and Border Protection didn't collect enough evidence to build cases, including the names of arresting officers, according to a US official familiar with the matter who was not authorized to discuss it publicly and spoke on condition of anonymity. Officials say the agent, along with a K-9, tracked the 36-year-old suspect to a remote desert area where the suspect struck the agent several times.
Homeland Security says it has identified 600 identified criminals within the caravan.
Prosecutors said the agent placed his body on Rodriguez's right arm to try to control gain control of the pistol, and the two men wrestled for about a minute until two other Border Patrol agents arrived.
"I didn't really have much of a plan when I left Honduras: everyone said that we would be able to cross the border - I thought it would be easier", said 29-year-old Yocelyn Alvarado as she picked up her 3-year-old son Fernando to stop him wondering into vast puddle of stinking floodwater and sodden trash.
On Thursday, as a steady rain fell and partially flooded the sports complex serving as the main shelter, it was Mexican police who stopped more than a dozen migrants from the caravan approaching the nearby El Chaparral border crossing.
USA customs and border control officers fired tear gas canisters into Mexico at dozens of migrants who tried to rush border fencing on Sunday.
Approximately 7,000 migrants remain on the Mexican side of the border demanding to be let into the United States. About 1,000 tried to rush the border and illegally cross into the U.S., Border Patrol chief Carla Provost said.
U.S. Border Patrol helicopters flew overhead, while U.S. agents held vigil on foot beyond the wire fence in California. They point to images of crying barefoot children running from clouds of tear gas after Sunday's clash as proof of the administration's inhumane treatment. They were accused of illegally entering the country, which is a federal crime. Still others escaped prosecution because in the chaos surrounding Sunday's incident, authorities missed pieces of information necessary to file charges, such as the names of the officers who made arrests.
USA authorities are working on a new system to better record evidence if similar circumstances arise, the official said.
CNN does not know the current status of those that were arrested. One woman from Honduras, Leida Reyes, told her she thinks this is better than what they lived with back home.
