Who says it’s not camouflage?
Or, they are bringing uniforms with them and they wear them when they are crossing through the wilds instead of likely to be seen among people.
Could be the photos would give away the photographers.
Delving into my area of expertise:
Where are the interrogation/human intelligence reports? All of these men coming over the border, uniformed, and no one has been detained and interrogated to uncover INTENT?
The so-called intelligence officer with his vast experience, offers nothing but assumptions.
Not buying it. These are criminal elements, some of them likely former or active duty Mexican military, getting paid to mule drugs and people. It’s not an army seeking direct violence with the US. It’s all greed.
