What subjects can i research in order to answer this question?...?

Can Bob sue the police for not coming to his aid after gloria had informed the police of the immenent attack resulting in Bob's permanent injuries?

gloria had previously warned the police about the attack bob was going to recieve before hand, she was told they would not go until he was actually being attacked

yes Bob can sue police. Al Sharpton won a piddly 200,000 because the police knew he was going to march the street s of Bensonhurst to protest that neighborhoods attitude, consequently he was stabbed and was afforded no police protection as other people in our city receive when they protest or have walks for one reason or another. Civil liberties ? Sharpton vs. City of New York.

yes but you have to be able to prove that she informed the police and that they did not come in time or whatever.

law?

Well i am wondering if Sue had anything to do with it first off. You might be able to file a complaint with the department, not sure if it will help. I would suggest you contact your local news affialiate.

I dont think you will have much luck, but you might try professional negligence as a research topic. If no crime was actually being committed, they dont have a duty to respond if they have other pressing cases at the time
