"The pretext of the raid was that two individuals from the group had reportedly sent out “simulated court documents” — summonses for a judge and a banker to appear before the Republic of Texas to discuss the matter of a foreclosure.

Ah, do be careful when attempting to overthrow the government, it tends to overthrow you, off the nearest bridge. And be careful who you associate with, they may be the wrong kinds since fringe movements like this are full of nutters.

Searching their vehicles would require a warrant for each vehicle because they we not in their vehicle at the time of contact. I see major violations of not only state law but of the fourth amendment also.
