Violent criminals are not the low hanging fruit. Violent criminals do not want to be found. Violent criminals do not check in and update their residence information and pursue the process of getting work permits and pursuing naturalization.

Immigrants who follow the process, who follow the law, who do what their told are the low hanging fruit. They are easy to find, and easy to push around. And easy to deport.

Republicans and ICE are too incompetent to find the criminals. They are going after the good immigrants, leaving the criminals alone, because that's the only way they can get anyone deported. They only care about boosting their numbers. Actually would prefer to have the criminals here, because if they deport all the criminals they won't have anyone left to hate.
