And yet, Engels himself made some concessions to bourgeois prejudices of the police issue. Actually, it took place only in the last years of his life when he thought no less revolutionary than in the era of the full flowering of its life forces, but when the powerful development of the labor movement after the 40 -year hopes and expectations made him somewhat underestimate the obstacles that have stand in the way of the labor movement. This happened as a result of the optimism that left Engels in the most dark and difficult days. And that's why we can not pass the mistakes he made in his last military pamphlet "Can Europe Disarm?". Engels tried to give her evidence in favor of the conversion of permanent armies, the police, based on a universal arms, perhaps even "for the current government, given the current political situation." It requires for this purpose in the first transfer of the center of gravity of military training to young adults and sees precisely in this point difference between his proposed militia system and other existing systems of the police, such as the Swiss.
