Unfortunately, most landlords in most states do not affirmatively undertake in writing in a lease or by the hiring of patrol officers that your apartment complex or apartment unit will be crime free.  If landlords did that and a crime occurred, you could potentially sue the landlord even if the landlord had taken precautionary steps.  So you really do not have any recourse against the landlord.  Make sure you notify the landlord and local police if a crime occurs but otherwise a landlord is not required to inform you of any crimes occurring, especially if it would interfere with police investigations. That being said, a crime occurring is not sufficient to get you out of the lease agreement you have with the landlord.  You can choose to approach your landlord about your concerns and ask if the landlord is willing to allow you to surrender the lease without any implications.
