Typically if you are doing manipulation of the value, you don't want to alter the input value, but rather a copy of it.
<Cfset var firstName = Trim(arguments.firstname) /> Vs <Cfset arguments.firstName = Trim(arguments.firstname) /> If you're not manipulating it further, then it might be a bit redundant at first: <Cfset var localfirstName = arguments.firstname /> But by writing it this way, you make sure that if further down the road, if you find out that whitespace is being added to the end of certain firstnames, and you want to add the trim operation, you don't have to add it for every reference to arguments.firstname. So it's a best practice in that it allows you for more maintainable code.
