Well yes. Joint and several, along with 99 John Does named at the outset. But motions to dismiss are relatively cheap (as filings go), if law and precedent is on their side. The thing is, if you are a landlord and you rent a house, do you worry if someone converts it clandestinely into a hair and nails salon? If you stay in a hotel room for a night, who is responsible if you set up a bookie operation and it gets busted by the cops: the hotel, or you? I am wondering if there is some legal principle involved that these situations illustrate. I imagine there may be. If so, I just do not know the formal legal theory and terms.
All they have to do is get it in front of the right jury.
