This is Mombasa. People heading to rural towns and there's only one ferry crossing. There was a 7 pm curfew in place. People were trying to beat the curfew and get home. As they were waiting cops came in and caused mayhem cause they were overcrowding.
This was two hours before curfew reached. Government hadn't offered them a solution how to get home while maintaining social distances but they got whooped and sprayed with tear gas anyway.
Note the issue the cops apparently had was over crowding but had no issue compiling into groups huddled up trying to avoid getting hurt
