Code Overview Confusion!

[TotallyNotAHaxxer]

Was looking through some of the code and realized there is some interesting logic flaws in it! One of them I pointed out was here.

func ExecuteTelemetry(index int) {
	filePath := helpers.FileInputString()
	switch in := index; in {
		case 1:
			output := helpers.OutputPathString()
			suite := NewDJI_Flight_Path_Map(filePath, output)
			suite.ExecuteFlightPathAnalysis()
		case 2:
			suite := NewDJI_TelemetryVisualizations(filePath)
			suite.ExecuteTelemetryVisualizations()
	}
}

When using switch case, you are using in := index; in

but never actually using the in variable! Is this variable used or exported else where? Maybe I am missing something! Just noticed that when running the tool on a debugger, this statement popped up a ton!
