About Ramblas! police was chasing the van, ambulances showed up less then 2 minutes after the attack. So, here's how it went: the suspect has a french driver licence , he rents the van, because he has a muslum named, rent car business informs the police, the police checked his residency, catchs a phone call, before he starts the attack. Police iniciates the chase, and calls ambulances to back up. Police didn't made no effort on stopping the van, by traffic police ramdom stops. The deal is, for the Jihad not be caught, do not rent cars, buy the vans on used cars sites with fake ID. Do not make phone calls on the previouse 24 hours before the attack.
