Since the US authorities, who see the Hell's Angel's as a criminal organization on par with drug cartels and terrorist groups, decided to ban entry to the US for non-American members, the group has held its annual congress in Europe.
This year is Poland's turn to play host to the bikers, and a local source in Rynia complained to Polish news portal Onet about a lack preparation on behalf of the authorities and the possible consequences.
He shed doubt on the level of adequate police preparation, including a failure to gain intelligence from other police forces abroad.
"In some branches of this club 80- 90 percent of members have a criminal record, for serious crimes like murder, robbery, assault with weapons, extortion, drug trafficking and people trafficking. Someone has to control them, because if there is any conflict, they will stop at nothing," he said.
A possible confrontation between the Hell's Angels and other motorcycle groups in Poland would end in "bloody carnage," he warned.
"That took place in the Czech Republic two years ago. There was even gunfire between conflicting clubs, in which a Polish Hell's Angel's member died and several people were shot."
"The police got there late, but when they did, they found a lot of dangerous items like firearms, knives and cleavers. That happened right at out border, so you to have consider that it could also happen to us."
"Allowing these people into Poland is simply a shameful mistake," Onet's informant concluded.
"On the eve of the NATO summit and World Youth Day, can Poland afford to have them undermine its image as a safe country? Why did it on the one hand refuse entry to the Night Wolves club, but a few weeks later allow in many more members of another club, which has had bad press worldwide for years?" he asked.
