ELI5: How can the President issue an executive order that basically directs an agency to ignore the law?

NO POLITICAL BS PLEASE.  Just explain the reasoning behind the president's proposed order that says don't deport who the law says we must deport.  I don't care about - or want to hear about -who is right or wrong on immigration policy.  My question has to do with the concept of the rule of law, not immigration.

The executive branch's job is to execute the law. 

For example a cop pulls you over for 5mph over and lets you off with a warning. This is within their right as they execute the law and can decided if the law needs to be applied in this situation, and if punishing you just.

This is an example of a power check in the US government. Congress can create a law, yet if the law is very unpopular, or stupid. It may never be enforced.

:.:.:

The president cannot create laws, or spend money without congress's blessing. But he can tell agents within his branch how to read the law, and execute it. That is actually what the President's job is.
