I haven't personally seen it, but I've heard from people who've witnessed it first hand. You can choose to go straight to medic, but during your internship things can get rough for you and your patient, depending on who you're interning under. There have been incidences where a medic fresh out of didactic and clinical's is on his/her first 24 as an intern, and they get a code and freeze, just straight up freeze. Not because they don't know what to do, but because they've never actually experienced, seen, or handled a situation like that. If you're the medic on scene, you're expected to lead and lead efficiently, so as to provide the absolute best possible outcome for the patient.
If you feel confident that you could handle a call such as that with no prior field experience, it's naive at best. Most schools who are training medics to save lives, not training medics so they get paid tuition, will want you to have 2 years field experience as a basic (preferably ET's, not IFT's), and around 6 months minimum if you're dialed in on your skills and have gotten some good patient contacts.
This being said, it's all up to you and what you feel is within your limits.
