I haven't seen much media focus on them yet. Security was terribly messed up but the Police officers on the ground were incredible. In the footage, the car comes to a stop and a baying Mob swarm and attack the driver. You see multiple Hi-vis' run to the car, fight off the mob to secure the drivers arrest and protect him (in as far as this their role) and form a ring of steel around the vehicle to apprehend him without complications. All the while they actually had no idea if that driver was armed, wearing explosives or if the car was packed with explosives and were at risk of aggression from the crowds turning on them.
Whilst the mob was understandable, if they'd had their way he'd be dead or cabbaged and we'd never have a true idea of what happened- I presume not only his answers but his demeanor etc will give a good insight into this.
As individuals on that day they acted with immense bravery. Hopefully their heroic stories will come out eventually.
