The “panic button” is the fear of losing all the remittance money coming into Mexico.
A "panic app" or effort to help its citizen avoid lawful action to report those illegally in the United States could be seen as an act of war.
Years ago while W was trying to invade Iraq I was saying we could be better off invading Mexico. Between the cartel activity of human trafficking, drug running & violence in our cities, the gov't corruption, pollution & problems of NAFTA & illegal immigration we could've gotten a better deal than the endless mid-east wars.
