The shady looking characters, and their guns, were spotted by concerned neighbours who rang the police. Unfortunately the cops were unable to do anything about them tailing Katie as the actress herself didn’t call them.
Despite questioning from journalists the men maintained a stony silence, however it’s believed they were member of that Scientology thing that Tom Cruise seems to fond of. This is something the cult themselves strenuously deny, saying:
‘We are not following Katie or conducting surveillance on her in the wake of her divorce with Tom Cruise'.
According to sources in the US, Katie saw these kind of tactics coming prior to the split announcement:
'Katie saw all the pressure -- [Scientologists] are professionals at pressuring people to be quiet. That’s why she did this in secret.’
'Suri is at the age where they are going to start educating her in Scientology centers and indoctrinating her into the religion.’
'Katie did convert when she and Tom were married, but she didn’t take to it. Behind closed doors, and when the private planes and the red carpets were gone, she didn’t like it. And she decided she does not want that for Suri.'
