It would be prescient for movies shot before 1996.
The concept is to store data optically in non-photosensitive transparent materials such as fused quartz, which has high chemical stability. Recording data using a femtosecond-laser was first proposed and demonstrated in 1996.
Governments should definitely have done a better job to ease tensions and avoid faith-based hate and backlash for muslims.
A good thing officials could do is explicitly oppose to the rhetoric of religioius war that Daech/Isis is trying to spread, and defend France's universalist model that aims and succeed in large part to have citizens of all faith peacefully cohabit.

I only mentioned his familiy's faith because you mentioned it. This murder is front page news and talked at length by medias, but your comment is the first time I heard of his supposed faith, so I went and checked.
It would be interesting to understand the motivation. This might be an attack on the school as an institution, which affects people of all faith.
There's no justification for killing innocent civilians, Jewish or not.
There's little doubt of the attacker motive given he invoked his god, and given the timing. But nothing suggest the teacher was personally targeted for his faith. He may have been the first person the attacker ran into.
The United Earth government in Star Trek looks almost as unrealistic as Faster Than Light travel.
A united earth government isn't contrary to any physics law I'm aware of, but that would take a strong political will, not just from leaders but from the general population, as well as a very long time.
The European Union has been a work in progress for 70 years to integrate different countries into one political system. Lots have been done, but it's still far from a small-scale United Earth. Every country hold onto its sovereignty, and a consensus from all 27 member states is required for many things, so it's moving rather slowly.
Impeding on people's view? Should have tought about this before building the damn thing. Having to put dots on the glass is a tiny price to pay to protect the ecosystem.
