By Karina Tsui, CNN(CNN) — A Tuesday night town hall in Memphis drew dozens of residents with questions about how a federal law enforcement surge will play out in the upcoming days and weeks. “All of this is about building upon the success that we’ve already built,” Memphis Mayor Paul Young told CNN affiliate WHBQ at the town hall. The deployment of federal authorities in Memphis is taking place alongside similar enforcement actions in cities like Chicago and Portland – where President Donald Trump claims crime has gone unchecked. A group gathered at Memphis City Hall Saturday to voice concerns about the operation, saying resources should be put into education, crime prevention, youth services and hospitals instead of federal troops. “I am glad they’re here,” Aqueelah Parker told WHBQ.
