Texas Crime

Texas crime rates are higher than national averages. However, the state prides itself on the lowest crime rates in the West South-Central region.

Sixty percent of Texans think crime is increasing in the state compared to 11 percent who believe it is decreasing. On a nationwide scale, 66 percent think the crime in the area is increasing, while eight percent said it is declining.

According to a Safe Wise report, Texas's most experienced crime was package theft, with 21 percent falling victim in the past 12 months.

Meanwhile, Texans expressed the second-highest overall concern about gun violence, with 61 percent saying they worry about gun violence every day.

Fifty-three percent are most worried about a gun violence incident happening to them. In 2020, Texas encountered 34 mass shooting occurrences, as compared to 30 in 2019. 

Forty-eight of the survey participants say they use some form of personal protection, which is higher than the national average of 34 percent.

Despite the number, Texas Gov. Greg Abbott has dismissed President Joe Biden's gun control measures, saying it was just for show.

Abbott said there is no acceptable way that a president by executive order can alter the Second Amendment rights, Independent reported.

Abbott noted that Texans need their Second Amendment rights to defend themselves, especially when the government is doing less to protect the public.
