Wow, that's microscopic. For context: "In 2016, out of 1.2 million people tried, only 1,039 were found not guilty - an acquittal rate of around 0.08%. In 2013, the conviction rate reached 99.93%, with 825 people acquitted out of 1.16 million people put on trial."
So, in a normal year, some 1,199,000 people are convicted. You didn't give a time frame for your 1300 convictions, but let's be super generous and assume that it covers the last 20 years. That means a whopping 65 immigrant convictions per year. If your data is from the past 10 years, 130 immigrant convictions per year. Honestly, I bet those numbers wouldn't even raise eyebrows in Little Rock.
