The latest FBI report lists Dallas as the most crime-ridden large city in the US. Details are here. Biggest problem, enormous numbers of burglaries. Why? In Texas, car burglary is merely a misdemeanor (see here and scroll to section 30.04) and Dallas is the car burglary capital of Texas.
Another reason: incompetence. The horrible and disgraceful Terrell Bolton FINALLY was sacked last year as police chief. But he never should have been hired in the first place. Hopefully the "proven crime fighter" (see FBI report article above) Kunkle will reverse Dallas' terrible trend.
