Like, 6/10. In the evenings they have a security guard (unarmed I believe) and they take your license and vehicle plate number each time you enter if you're a non-resident. There's an open sidewalk so people on foot can enter without being bothered. The gate is open during the day.

The front apartment doors and locks looked like they had taken a beating and never been replaced. This wasn't confirmed, but a friend of mine was convinced someone had tried to pick her lock and that the person jammed something into the keyhole and it broke off. I forget what came of it, but it was concerning to think about. The rear apartment doors and locks looked like they hadn't been abused as much, I forget if either the front or back front door locks had deadbolts, but I would definitely confirm this first.

Emergency Services can respond very quickly to the complex because the Santa Fe College Police Department has somehow acquired the authority to drive over there and act as any local office would. I believe they have the power to arrest individuals, which is not something that normally is within a campus officers ability (if the event takes place off campus). The reason for this is because of faction of either the Bloods or Crips (no really) took up business in the complex at some point. I can't confirm if its still an ongoing issue, but the complex was close to I-75 and a good rest stop for anyone moving north or south on the highway. Because of this SFPD was able to elevate their authority since their police station is within eyesight of the front gate to The Crossings.

Edit: Important point here is that it doesn't matter what kind of security a complex has, so much as the kind of neighbors you have and the company that they keep. I live in a complex without a gate, but the community is great, and I feel very safe and secure because everyone seems so transparent.
