If Congress wanted to take care of the first responders in New York but also adhere to the rule of law, they would have specified the criteria that needed to be met for the law to apply: responding in the line of duty, suffering harms not already provided for in existing health benefits, etc. To pass such a law, it is necessary to think through what principles we are choosing to be governed by, because once the law is passed, it will apply to everyone who meets whatever criteria the law establishes.
