EU border wall, sound weapons, AI lie detection
In order to keep out migrants several EU countries are building border walls (nevermind their negative response to the 2017 Trump proposal), employing sound cannons, and working on an AI lie detection tool.
Analysts have commented that often these types of tools, implemented for such causes as migrants, are tested out before being turned on the citizens of the countries that built them.
They also note that the steps will possibly result in more deaths, as the migrants will turn to smugglers and other more dangerous methods of entering Europe.
