Because of this, we are going to learn everything there is to know about this Allen guy, his name is going to be famous all over the socials and RWM, which will associate him with the Democrats and the mainstream media, all while nobody remembers anything about the guy in Butler (quick, without looking it up, do you remember his name?) because a "public statement from (then) FBI deputy director Paul Abbate described [the Butler shooter's] activity on social networking services as including comments that 'appear to reflect antisemitic and anti-immigration themes'", which is inconvenient since those views align with those of Trump's base.
