Missed that one, and an extraordinarily bad idea (unless you actually do need medical attention).
Unless it's true, you would be lying. and lying will always be used against you. It establishes doubt as to your credibility. Once you are caught in a lie, you are a liar; and people, including people who you very much need to believe your story about your having to defend yourself, will doubt everything you say.
You may think you won't get caught, and maybe you won't. But that's a different question. And liars frequently get found out.
In addition, you have now called for an ambulance you really don't need. Depending on the availability of emergency medical services in your community, you have taken an ambulance out of service and perhaps delayed response to someone who really is gravely sick or injured and really needs one.
You're also now using space and resources in an ER -- space and resources you really don't need. You may be thereby delaying care to someone who really is sick or injured.
And are you going to file an insurance claim for emergency medical services, which you knew you really didn't need? That's insurance fraud and grand larceny.
So when all that is discovered, you now become a callous, lying monster wasting limited emergency medical resources so you can duck talking with police (when you merely have to invoke your right to remain silent) and delaying the availability of those services for people who may really need them. You also expect your medical insurance to pay for your little ruse, even though they have no responsibility to pay for unnecessary service used for the purpose of temporarily evading police questioning; and thus you are stealing from your medical insurance.
But nonetheless you will expect the police, the DA, the grand jury and possibly a trial jury to believe your claim that you were an innocent victim forced by the criminal act of another to use violence as a last resort to save your life?
Good luck.
Whatever else, don't lie (and don't run).
