He went on to argue that the squatters had the potential to cause millions in damage to surrounding houses and the police were right to react so quickly.
"You've come on the radio programme Richard, without realising it, [to say] that people aren't equal before the law, it's determined by the value of the house you own."
The caller denied James' claims, telling him that the quick response may have been because "they may well have been around the corner."
"Last time I got burgled it took a day and a half for them to come around", James said, before the ex-officer saying his claim was false.
"I was there!"
"Where is the threshold? How much does my house have to be worth in order for police officers like you think it's worth bombing around there at 100 miles an hour?"
The caller insisted that "poor people do" get the same response to the scenes in Belgravia, to which James reiterated his first point.
