There are variables in that statement i.e. called as a witness against whom? If you're making a statement against your spouse you can claim spousal privilege.
I'm speaking specifically to whether or you the person called requires representation. Nearly anything can be qualified but in general giving statements to the police about something you're involved in only as a witness and without charges is fairly routine.
If I were a suspect in a burglary and I could show evidence that I was 100 miles away from the scene of the crime and had dozens of witnesses to corroborate that, why pay a lawyer hundreds if not thousands of dollars when the matter could easily be handled by cooperating with the police?
Again, a person can qualify a thing, set up just about any sort of hypothetical that would tilt a board, but in general, supra and prior.
Also, if you have an alibi that will check out, terrific, but mostly your scenario isn't how it turns out. Often charges and investigations take some time and it's perfectly normal to be fuzzy on what you were doing and where you were, to say nothing of lacking corroborating data at the time you're being asked. Better to speak through counsel after the two of you have gone over the specifics and you're certain of your answers.
No matter how innocent you are, the police don't know that and if they're looking into you they believe they have reason. Anything you give them to fan that fire isn't helping you, even if they tell you they're just looking for the truth and would love to write you off as a suspect.
Police can and often will lie to you in order to get you to say something incriminating.
It's human nature for the guilty to be nervous, the innocent know that the police are their friend and wouldn't be nervous if they were telling the truth.
See, if I ever believed you were a law enforcement officer that alone would have completely turned me around. You literally don't appear to have any experience on the point with that comment. Not even remotely true.
Another myth is the belief that only guilty people appear nervous. This idea assumes that a person who has nothing to hide has no reason to be nervous or to demonstrate fidgeting and anxiety often associated with deceit. Questioning by law enforcement can be stressful for anyone, especially someone with little understanding of the criminal justice system. That anxiety can be heightened by accusatory questions or an aggressive interviewing style. Not surprisingly, innocent individuals often demonstrate many of the stereotypical behaviors associated with deception, including speech errors, fidgeting, and gaze aversion.
