So those may have been cops?
Yes.

The Not-So-Sudden Jihad Syndrome in Nice

(There is also a very critical news video captions in English below.)
While the time has come for tributes and speeches, the investigation of the Nice attack is advancing
0:07 in baby steps. The profile of the killer becomes clearer. Mohamed, who was of Tunisian nationality
0:12 and not of double nationality, as we were being told before,
0:16 would have largely premeditated his actions,
0:19 a preparation shattering hypotheses of being mentally unstable.
0:22 Benjamin Nicolas: Questions about killers profile gradually fade.
0:27 Mohamed Lahouaiej Bouhlel, 31 years old, a Tunisian residing in France,
0:31 and a residence permit-holder for the last eight years had indeed premeditated his actions.
0:36 Research about his past revealed that his father had been a member of Ennahda,
0:40 a Tunisian Islamist party, not exactly known for its moderation.
0:43 Mohamed Lahouaiej Bouhlel was first introduced as suffering from depression, depressed
0:48 because of his divorce, and turned against society, and whose radicalization was, as always, sudden.
0:53 He had no file S [a terrorist record] but was under judicial review
0:56 for violent acts unrelated to terrorism.
0:59 Until now he had complied with those measures of control.
1:02 Anyway his crime was well thought-out:
1:05 apart from renting the truck, he repeatedly made marks on the slaughter route,
1:10 without arousing suspicions of law enforcement,
1:13 even though Nice is one of the French cities most monitored by cameras.
1:17 The terrorist managed to evade all the measures; the measures, all in all, rather light,
1:21 since no fences or concrete obstacles were installed
1:25 to prevent vehicles from entering the pedestrian zone.
1:28 It is partly for this reason that the vehicle could travel more than two kilometres
1:31 before being stopped by police bullets,
1:34 also by the municipal police, who were armed, fortunately.
1:37 Tired out, no doubt, by the very high security measures during Euro Soccer,
1:41 the security forces there were, according to Christian Estrosi, the president of
1:45 the PACA region [Provence-Alpes-Côte dAzur] insufficient for the supervision of July 14;
1:49 the 84 dead and dozens injured, still between life and death, are the most striking results of it.
1:54 There was a delay in admitting that this event was a terrorist attack.
1:58 Instead it has been presented as an isolated act. A claim by ISIS in its propaganda newspaper
2:04 ended the hesitation, even if claims after the fact
2:07 should always be taken with caution. A message found on Mohameds phone
2:12 makes the investigators believe that he probably had accomplices.
2:16 A total of seven people were taken into custody, including a couple of Albanian Muslims.
2:20 They all have described the terrorist as a violent man.
2:23 Faced with this new attack striking France full force,
2:26 the socialist government is concentrating conveniently on paying their respects, to avoid drawing
2:30 any conclusions from their failure. The mourning time is constantly being mentioned
2:34 to make people accept the shocking and permanent lack of action.
2:37 While attacks accumulate on our territory, no resignation has been announced yet:
2:41 neither the minister of the interior nor local prefects from affected towns;
2:45 on the contrary, any critical commentary on the insecurity prevailing in France
2:49 is considered improper by the socialist government. The only permissible discussions are those
2:53 concerning compensation for victims, but that doesnt seem to be handled better then the security.
