Segregation within the grounds, and also security checks, need to be a heck of a lot better than that.
I'm not sure what can be done in the towns at the moment. England could be back in Marseille later in the tournament. However the authorities will be very concerned if Russia were to win the group - there would be a good chance of meeting Ukraine which will be carnage.
I have concerns about Thursday. No alcohol in Lens. Wales and England fans wanting a drink or travelling will be going through Lille. Russia are playing in Lille on Wednesday. Recipe for it all to kick off again.
