Anti-Kettling techniques

I have been looking at the recent demonstrations in the UK over tuition fees and was wondering why the demonstrators don't split up in to many different groups as soon as they see police congregating instead of waiting to be kettled when it is too late to do anything, or why not plan marches to have multiple groups?

>but around here the students are much more politically mature than the rest of society.
hahaha this is what commies and traitors actually believe.

Hint: Actual communists(jews) view all of these sorts as USEFUL IDIOTS, to be purged once the goals have been achieved.
