I could be wrong about this, but I think that a JSA or JLA member actually COULD throw you out of your house. Both groups have been around a long time, they've got major heavy-hitters amongst their members, and they have at least enough clout with the government to be allowed to have bases in areas that otherwise would be off-limits (the JLA has a base on the MOON, forcryin'outloud, which you'd think would generally be objected to, and the JSA has what is basically a 'JSA building' right out in public). Their word that something is rotten in the state of Denmark - or the house of the Browns, in this case - would probably carry enough weight that the cops would check the situation out, at least.
