Dispatchers in Liberty County’s 911 center spend hours in front of computer monitors in a dimly-lit, windowless room fielding calls that they don’t know whether they’ll be about a noise complaint or a shooting.This week, the men and women who are the first to get calls for help were recognized by a recurring congressional proclamation of National Public Safety Telecommunicators Week. Every year the second week of April is set aside to thank the operators who do an often thankless job. According to Liberty County 911 Director Tom Wahl, the county also issues a proclamation to coincide with the national one.Aside from earning a living, Shanquanette Williams said she took the high-stress job more than 10 years ago because of her nature.“It’s all about helping people,” she said.
