NYPD consulted with City of London Police in the last few years to develop a kettling technique to stop all forms of marches that are not of the “proper type of poodle marching”...
called kettling, a bunch of grad students in London developed a free software platform that is anonymized P2P mobile that allows live updates through social media to create anti-kettling amrch plans.
NYPD is not prepared for this, and quite frankly, it’s not possible to stop a dozen plus marches coming from 15+ locations in Manhattan/Brooklyn today.
Excess in your emotive weighing of surety leads the disinterested observer to the antipodal thesis.
