Could the Manchester Arena bombing be a copycat of Boston Marathon bombings?

April 15, 2013 the Tsarnev brothers put bombs at the finish line of the Boston Marathon.  They put pressure cooker bomb are set off towards the end of the race. For nearly a week these pieces of garbage scare the nation.  Eventually the older brother Tamerlan is killed by agents in a gunfight in Watertown west of Boston later that week.  The younger brother Dzhokhar wounded in a boat in the same town.  Tamerlan is buried in an unmarked grave in the DC area.  Dzhokhar is sentenced in a federal prison on death row.  

Now forward the time machine to May 22, 2017 at the end of the Ariana Grande Concert in Manchester, England.  A suicidal bomber named Salwar died in the bombing though he would add his own fireworks to the concert so far has killed 22 people.  Recently thanks to a Libyan militia leaders his brother Hashem and father Ramadan were arrested in Tripoli.  They aid him by providing technical assistance to their piece of trash brother.  British authorities immediately bring these pieces of trash to the UK as accomplish to the Manchester arena bombing.  They are currently being held.  Again please pray for the victims of this tragedy and play an Ariana Grande song to remember these victims.  Manchester the world is with you.  These pieces of trash will get justice.  If the Manchester Arena bombing is a copy of Boston Marathon bombing then there maybe more copycats in the future.
