Dozens killed in Nice as truck mows people over at Bastille Day celebration

Five people arrested - two for selling illegal weapons.
Killer may have been planning to commit an action for months - among his searches he seems to have read an article about a truck ramming into a shop window on Jan 1st. Authorities do not know whether it’s another example of his morbid curiosity or if the idea of the mass murder was born then.
One of his friends was a drug dealer who owned a Kalashnikov but nothing points to him wanting to use it for an attack. He claims it was to protect his cocaine business.
The big news isn’t that though. The big deal is who knew what when after the attack.

Isn’t there still some controversy over who should have blocked off the promenade? I hate to see this lead to infighting…
