Among the variety of possible SM extensions, LHC searches pick selected
models, often simplified models, and select some new physics signatures to
guide the searches. The implicit hope is that with this procedure we cover
all the reasonable new physics signatures. But the devil is in the details.
I will show some examples of well-motivated models with additional gauge
bosons where one might near-miss the new physics signals in current
searches. Or where experiments might find apparently contradictory results
in searches apparently equivalent.

On a more experimental ground, I will discuss the results in diboson
resonance searches, where 7 anomalies or so appear at the 3sigma level. This
fact suggests that the above discussion and examples may be not only
academic, but of relevance for actual experiments.
