Well, difficult to evaluate but given the numbers, of course France is home to the french army but clearly times have changed and, if regretable, it is impossible to ignore that a significant part of today's french population would support a taliban style political stand if not regime when assessing risks to plan security for military base, personnel and their families. Military facilities home to troops engaged in a foreign war should be under maximum security and personnel briefed. If it had been the case, whatever the ongoing investigation in the shooting will uncover, the shooter would have been shot down by the escort or prevented to act.
