I wish to voice my concern about the provocative tactics employed by Sussex Police at the anti-arms trade march on Saturday.

As I was handing out leaflets to interested passers-by, I was often man-handled by police and on one occasion was thrown back into the march.

Onlookers expressed their disbelief at such excessively physical police behaviour.

It is a tribute to those on the march that it passed so peacefully in the face of such harassment.
