Can you buy and sell bitcoin with cash in person?

Can you please elaborate on the process of buying and selling Bitcoin with cash in person? I'm interested in understanding how this transaction works, specifically the steps involved, any potential risks, and whether it's a secure method for cryptocurrency trading. Also, I'd like to know if there are any legal considerations or regulations that I should be aware of when engaging in such transactions. Additionally, are there any recommended platforms or meeting points where these cash-based Bitcoin transactions are commonly conducted? Thank you for your insights.
