Phones buzzed across Texas just before 8 p.m. Wednesday with a high-priority emergency alert. But it wasn't about flooding, a storm, or a missing child. It was about a five-day-old shooting at an ICE detention center hundreds of miles away.

The Texas Hill Country floods brought questions about the alert systems in place for emergencies. But data shows some Texans may be suffering from “warning fatigue."

Officials are being pressed about their response and whether there could have been a better warning system.
