A look at the police presence at the Grand National horse race at Aintree.
Item title reads - The Police Parade. Aintree, Liverpool.
L/S of what seems like hundreds of police officers in uniform stood together at the Grand National, the camera pans across them. M/S as they all stand in lines, certain constables are called out by officers and stand in a line, the camera pans back and forth across the rest of them. An officer walks down the line showing something to them, it looks like a piece of card. Two rows turn and march off to police the race.
