As the footage shows I was stood basically in front of the step ladder making sure I could get a good angle on every speaker, the following events I am about to describe I did not get on camera as my focus was to ensure filming the speakers as opposed to documenting the activities of those around me. About 20minutes (During parts 4/5) into the rally a man dressed all in black swooped up to the step ladder, keeping very low to the ground, tipped the contents of his bag out and exited in an incredible speed. Left on the floor was roughly six small black packages. This suspicious behaviour instantly caught the attention of myself and others around me. I lightly stepped on one of the packages, could feel it was hard and gently flicked it to someone stood about a metre away. All the time still filming the speaker! The person next to me used his foot to open the package, aware not to put fingerprints on it, and a catapult was revealed. Everyone was very conscious that these weapons had no place at a public rally and were kicked by various people, though not myself, under the metal fence that can be seen in the back of all my footage into a fenced off mounded area of waste ground and out of harms way. One speaker, a ginger gentleman sporting a special brew can, warns the crowd intially of the catapult saga as he had an arguement with a cameraman who was going to keep one! Thankfully they were convinced to throw it also under the fence.
