Stop and searches on I-10?

for those that complain think about what they do in other places. My BIL was raised in mex, his sister born there. Anyhow some years ago she needed proof of birth info, so they went to the local church to get the information required. This is in interior mex. Anyhow after a while the federalies came up with weapons drawn, ordered everyone out and then proceeded to 'search' the motorhome. No reason given, my BIL speaks mexican and they just told them to stay away and be quiet. So if you have a little inconvenience in going thru a check point, just think what it could be. Yes I am retired mil, have had my vehicle searched upon entry to the installation, but have never had any issues with the BP other than some are lazy and dont do much. If you dont want to be stopped I guess you can just modify your travel area to avoid the KNOWN inspection stations! Just think about 15 years ago you had to go thru agricultural inspections in some states and actually surrender any fruit, vegetables, flowers you had in your possession, no one I know of complained then and you actually LOST items under your control.
