(CNSNews.com) -- As part of his plan to fight crime and violence in the United States, President Donald Trump stressed that the wall along the southern border "will be a big help," and he added that he is implmenting a "zero tolerance police for acts of violence against law enforcement."

"The wall is getting designed right now," said Trump in a Feb. 8 speech before sheriffs and police chiefs of the Major Cities Chiefs Association (MCCA) in Washington, D.C. "A lot of people say, oh, oh, Trump was only kidding with the wall. I wasn’t kidding."

"No, we will have a wall," he said. "It will be a great wall, and it will do a lot of -- will be a big help. Just ask Israel about walls. Do walls work? Just ask Israel. They work -- if it’s properly done."

As for further protecting the people in law enforcment, Trump said, "You have asked for the resources, tools and support you need to get the job done. We will do whatever we can to help you meet those demands."

"That includes a zero tolerance policy for acts of violence against law enforcement," he said. "We all see what happens. We all see what happens and what’s been happening to you. It’s not fair."

"We must protect those who protect us," said the president. "The number of officers shot and killed in the line of duty last year increased by 56 percent from the year before."

He continued, "Last year, in Dallas, police officers were targeted for execution –- think of this. Who ever heard of this? They were targeted for execution. Twelve were shot and five were killed. These heroic officers died as they lived -– protecting the innocent, rushing into danger, risking their lives for people they did not even know, but for people that they were determined to save. Hats off to you people."

"These slain officers are an eternal monument to all of the men and women who protect our streets and serve our public," said Trump. "We will not forget them, and we will not forget all of the others who made that final sacrifice in the line of duty. God has blessed our nation to put these heroes among us."
