Can I sue a Liquor Establishment for not calling Law Enforcement?

Can I sue a business in the following situation. I walked out and was aulted violently. I made my way back into the establishment (where I was a customer) and asked for help to call 911. The employees ignored me and left me there bleeding, purposely shunning me and my request for help and to use a phone. One person finally gave a phone to me and 911 had me go look for the license plate, when I attempted I was aulted more aggressively by multiple people in the parking lot of the business. The workers and staff there know who the ailants are and told officers they did not. I never had any communications with the people that aulted me, I seen them inside talking with staff members as if they were friends. I honestly walked out and got beat up, walked in and was refused help, called 911 and went out at their request for a plate, and was aggressively and violently aulted. Cops came, did nothing, ems came to check me but left, I had a ride take me to the hospital being I was in and out of consciousness from the punches and kicks to the head and face. These guys would have not got out of there and away from the law enforcement if someone would have helped me when I asked or if they would have gave the names to the officers.
