shouldn't EU also investigate this a little?
Saying defrauding others does not seem right to me. If you defraud a distributor of EU funds, that may have impacted EU funds; they would have a claim.
Do you have a source for your assertion?
Surely embedding a remotely triggered off-switch, as a vulnerability for military and commercial trains (and the overall supply chain logistics) would merit some kind of investigation?
Can't anyone with an antenna in a semi-close proximity spoof GPS signals that would engage these mechanisms?
