politicians and obstacles

it doesn't matter the time of the day, if you drive your car, you have many chances to be overcome by some politicians travelling with five cars and thirty soldiers each of them. then you wonder: here are they going everytime? why are they always is such a hurry? are they escaping someone who wants to kill them? have they just killed someone? has a revolution started? maybe not, they are just going to the restaurant.
apart from that, yesterday soldiers put some oil barrels in the middle of the main road, i guess to better check the cars passing (sometimes they do that). but the nice thing is that they do not signal it at all, and maybe at one moment they leave. so during the night you risk to bump into them (it's not easy to imagine that suddenly and apparently without any reason they put some barrels in the middle of a road where you passed two hours before and were there wasn't anything).
