Let's look at the facts: It is alleged that LG employees destroyed Samsung property in Germany. For starters, the only place where this should possibly go to court is Germany. None of the business of the Korean police at all. The crime happened in Germany. It's like one Korean CEO punching another Korean CEO in the face _in Germany_: We all enjoy it, and the first CEO would be questioned by police and go to court and possibly to jail _in Germany_.
Second, offices of LG in Korea have been raided. What evidence did they expect to find? For a raid (which I assume is just a search with a warrant, and lots of police arriving because it is a big office), the police would have a reasonable expectation to find proof of a crime. Well, in Korea, there is of course another explanation: If Samsung calls the right minister whom they own, any search warrant will come forward immediately.
But then a raid on an LG factory? What evidence in connection with a purported case of vandalism are the police expecting to find in an LG factory? Only possible explanation, same as above.
CEO not allowed to leave the country? That's getting bizarre. Do they think he won't come back? Never heard of bail?
I think it's getting time for LG to buy some politicians themselves. Worst case if someone gets convicted, they can then expect a pardon, like Samsung's ex-CEO (convicted for tax evasion).
