this is where the whole problem lies. The license allows you to weed out many "one-day detectives" who do not work under contracts or do not have ip. (that is, they are not responsible for anything), and most importantly they don’t see the development of their business, they work on the pitch from friends, acquaintances, etc. that is, they turn it into a hobby and not a business! secondly, the license eliminates this kind of detectives who think that they are "detectives" without previous work experience. in general, I want to say the following: if you really want to become a detective, then you must get a license, everything else is against the maral and threatens a big problem for you, and for us undermining detective activity in general. (imagine that you woke up in the morning and decided to become a policeman, went outside and started to administer justice), becoming a detective the first priority for you should be the legality of your actions, but methods are another question the main goal. you also need a license to enter the market and work with enterprises, without a license no one will even talk to you.
