I heard Dallas wasn’t so bad, but others are damn ruin life bad. It’s luck of the draw and how you want to deal with it.
Some of the worst are the ones you’d least expect - many of the really bad ones are rural towns where the LEO are on a power trip.
Someone in TSRA once told me that there was a pretty good correlation between towns that were speed traps and towns that were bad for 2A or self defense. Never got a look at the numbers, but from a few incidents I’ve heard of he may have had the right of it.
