at least

[arademaker]

As pointed by @leoalenc, we have 3 different analysis for at least in this corpus:

# sent_id = w01131060
# text = At least 330,000 people, including 10,000 technicians, were involved.
1 At at ADP IN _ 2 case 2:case _
2 least least ADJ JJS Degree=Sup 3 nmod 3:nmod:at _
3 330,000 330,000 NUM CD NumType=Card 4 nummod 4:nummod _
...

# text = The world may be enraging and absurd – yet at least someone has the self-respect to keep protesting against that fact.
...
10 at at ADV RB _ 13 advmod 13:advmod _
11 least least ADV RBS Degree=Sup 10 fixed 10:fixed _
12 someone someone NOUN NN Number=Sing 13 nsubj 13:nsubj _
13 has have VERB VBZ Mood=Ind|Number=Sing|Person=3|Tense=Pres|VerbForm=Fin 5 conj 5:conj:yet _
...

# text = That led to revelations over the last two days that at least six other Quebec journalists were targeted by provincial police surveillance operations.
...
11 at at ADP IN _ 13 advmod 13:advmod _
12 least least ADV RBS Degree=Sup 11 fixed 11:fixed _
13 six six NUM CD NumType=Card 16 nummod 16:nummod _
...

The last two as fixed but the second one does not modify someone but the verb. The last one modifies the six and POS differ anyway.
