Why is the number of illegal immigrants arrested at the US-Mexico border increasing?

On June 7, according to the US report, although the Trump administration adopted a "zero tolerance" policy towards illegal immigrants and even separated them from their children in order to prosecute illegal immigrants, the number of illegal immigrants in the US-Mexico border area increased by more than 2,000 in May this year.

According to NBC News, figures from the US Customs and Border Protection show that the number of illegal immigrants arrested by border patrol agents at the US-Mexico border has increased from 38,234 in April to 40,400.

Including those who surrendered themselves at the port of entry, more than 50,000 immigrants entered the United States through the US-Mexico border, which was the third consecutive month that the number of illegal immigrants exceeded 50,000.

The number of unaccompanied children smuggling increased from 4302 in April to 6405 in May; The number of parents taking their children out for a trip decreased slightly.

Tyler Q. Houlton, a spokesperson for the Department of Homeland Security, said that although the Trump administration has restored the rule of law, snakeheads, traffickers and bad guys understand our loopholes and use them.
